We shouldn't gratuitously make things easier for the AI player, but rules functioning to keep both parties in character seem like they can only improve the experiment as a model.

I'm less sure about requiring the gatekeeper to read and consider all the AI player's statements. Certainly you could make a realism case for it; there's not much point in keeping an AI around if all you're going to do is type "lol" at it, except perhaps as an exotic form of sadism. But it seems like it could lead to more rules lawyering than it's worth, given the people likely to be involved.
