It helps to know the contexts in which the term is often used, how it is motivated, and where the term probably came from. Thus, it is important to know the term in relation to other terms.
I haven’t heard the term “epistemic state” used often in the community, but depending on the context in which the person used the term, I imagine the person using it meant their overall “epistemic status” for a collection of claims (or their confidence in any given claim).
An epistemic status describes how confident a person is in a particular argument or idea. If the claim is important enough it is denoted with a percentage value that represents the probability that the cliam is true (from the person’s point of view). This is a good practice of reasoning transparency, because “plausible” can often be interpreted to mean different degrees of confidence.
As an example of how lacking transparency can lead to falure, when JFK questioned the Joint Chief of Staff about the chances of his plan’s success for the invasion of Cuba, the response was a “fair chance” of success, so JFK invaded. It was only later that “fair chance” was explained to mean a 1⁄3 chance of success.
As for the word epistemic more generally, it is indeed related to knowledge, but within the context of the Effective Altruism and lesswrong community, we care about the quality of the knowledge, not just quantity (since an effectiveness mindset leads to more positive change). This is why Epistemic hygiene (I hear epistemics used synonymously within the community, and it’s generally the word I use more) is emphasised so much (and why the sequences are so popular). It is very important for accurate beliefs to spread, so figuring out how to develop a set of community values that encourages accurate beliefs is what lesswrong is largely about.
I would say that the community is focused on how to have good epistemics in practice, rather than exploring foundations, although it does have that. The foundational roots of the term epistemics likely comes from the field of epistemology (this link leaves out some stuff, but it’s an okay starting point).
