Even after reading your post, I don’t think I’m any closer to comprehending the illusionist view of reality. One of my good and most respected friends is an illusionist. I’d really like to understand his model of consciousness.
Illusionists often seem to be arguing against strawmen to me. (Notwithstanding the fact that some philosophers actually do argue for such “strawman” positions). Dennet’s argument against “mental paint” seems to be an example of this. Of course, I don’t think there is something in my mental space with the property of redness. Of course “according to the story your brain is telling, there is a stripe with a certain type of property.” I accept that the most likely explanation is that everything about consciousness is the result of computational processes (in the broadest sense that the brain is some kind of neural net doing computation, not in the sense that it is anything actually like the Von Neumann architecture computer that I am using to write this comment). For me, that in no way removes the hard problem of consciousness, it only sharpens it.
Let me attempt to explain why I am unable to understand what the strong illusionist position is even saying. Right now, I’m looking at the blue sky outside my window. As I fix my eyes on a specific point in the sky and focus my attention on the color, I have an experience of “blueness.” The sky itself doesn’t have the property of phenomenological blueness. It has properties that cause certain wavelengths of light to scatter and other wavelengths to pass through. Certain wavelengths of light are reaching my eyes. That is causing receptors in my eyes to activate which in turn causes a cascade of neurons to fire across my brain. My brain is doing computation which I have no mental access to and computing that I am currently seeing blue. There is nothing in my brain that has the property of “blue”. The closest thing is something analogous to how a certain pattern of bits in a computer has the “property” of being ASCII for “A”. Yet I experience that computation as the qualia of “blueness.” How can that be? How can any computation of any kind create, or lead to qualia of any kind? You can say that it is just a story my brain is telling me that “I am seeing blue.” I must not understand what is being claimed, because I agree with it and yet it doesn’t remove the problem at all. Why does that story have any phenomenology to it? I can make no sense of the claim that it is an illusion. If the claim is just that there is nothing involved but computation, I agree. But the claim seems to be that there are no qualia, there is no phenomenology. That my belief in them is like an optical illusion or misremembering something. I may be very confused about all the processes that lead to my experiencing the blue qualia. I may be mistaken about the content and nature of my phenomenological world. None of that in any way removes the fact that I have qualia.
Let me try to sharpen my point by comparing it to other mental computation. I just recalled my mother’s name. I have no mental access to the computation that “looks up” my mother’s name. Instead, I go from seemingly not having ready access to the name to having it. There is no qualia associated with this. If I “say the name in my head”, I can produce an “echo” of the qualia. But I don’t have to do this. I can simply know what her name is and know that I know it. That seems to be consistent with the model of me as a computation. That if I were a computation and retrieved some fact from memory, I wouldn’t have direct access to the process by which it was retrieved from memory, but I would suddenly have the information in “cache.” Why isn’t all thought and experience like that? I can imagine an existence where I knew I was currently receiving input from my eyes that were looking at the sky and perceiving a shade which we call blue without there being any qualia.
For me, the hard problem of consciousness is exactly the question, “How can a physical/computational process give rise to qualia or even the ‘illusion’ of qualia?” If you tell me that life is not a vital force but is instead very complex tiny machines which you cannot yet explain to me, I can accept that because, upon close examination, those are not different kinds of things. They are both material objects obeying physical laws. When we say qualia are instead complex computations that you cannot yet explain to me, I can’t quite accept that because even on close examination, computation and qualia seem to be fundamentally different kinds of things and there seems to be an uncrossable chasm between them.
I sometimes worry that there are genuine differences in people’s phenomenological experiences which are causing us to be unable to comprehend what others are talking about. Similar to how it was discovered that certain people don’t actually have inner monologues or how some people think in words while others think only in pictures.

As I understand it, the idea would be that, as weird as it may sound, there isn’t any phenomenology to it. Rather: according to the story that your brain is telling, there is some phenomenology to it. But there isn’t. That is, your brain’s story doesn’t create, lead to, or correlate with phenomenal blueness; rather, phenomenal blueness is something that the story describes, but which doesn’t exist, in the same way that a story can describe unicorns without bringing them to life.

Doesn’t this assume that we know what sort of thing phenomenological consciousness (qualia) is supposed to be so that we can assert that the story the brain is telling us about qualia somehow fails to measure up to this independent standard of qualia-reality?
The trouble I have with this is that there is no such independent standard for what phenomenal blueness has to be in order to count as genuinely phenomenal. The only standard we have for identifying something as an instance of the kind qualia is to point to something occurring in our experience. Given this, it remains difficult to understand how the story the brain tells about qualia could fail to be the truth, and nothing but the truth, about qualia (given the physicalist assumption that all our experience can be exhaustively explained through the brain’s activity).
I see blue and pointing to the experience of this seeing is the only way of indicating what I mean when I say “there is a blue qualia”. So to echo J_Thomas_Moros, any story the brain is telling that constitutes my experience of blueness would simply be the qualia itself (not an illusion of one).
