There is a third possibility: Dumbledore brought in the troll to guard the Stone (or other object), as in canon, and he was the one who cast the spells to protect it. I’m unsure about this, because it seems unusually violent for Dumbledore.
In canon “Troll” was defense layer number.. 5? Anyone in that deep can fairly be considered to be asking for it. If this is the case, the naive reading of events is that it got loose because someone was cracking the defenses…
In canon, there were two different trolls: One that got in and attacked Hermione, and one that was guarding the stone. Two totally different trolls, although many have noted that both were supplied by Quirrell. (And actually, because of this it has become fanon that Quirrell has a talent in dealing with trolls. (Although that Quirrell is a very different person from HPMOR’s Hansonian Quirrell, so don’t read to much into this with regards to HPMOR.))

I believe that Quirrell actually stated this in canon. When he admitted in the chamber which held the Philosopher’s Stone that he was the one who had supplied the troll for the defenses, he said he had a knack for dealing with them, or something to that effect.
There’s ‘Lumos’ but it’s never mentioned as a dead-useful defense against trolls so presumably isn’t as good as real sunlight or a sunlight-generating spell.
Oh snap. I didn’t even notice that problem.

Why would Dumbledore enchant the troll against sunlight if it was going to be in the third-floor corridor all along?
To defend it against anyone with a sunlight-generating spell or who has some acorn potion handy.
In fact, isn’t there such a spell used in Canon?

No, I could swear there was an actual … maybe in one of the movies?
EDIT: I was thinking of this
