I would only make the AI bet if I had a read on the guy and thought he was trying to steal with two face cards or any A. All things being equal(i.e. no read), I think it's a fairly easy fold in that particular situation, being that close to ITM, as hard as it is to lay down AK especially if you're not getting any cards. You're not in desperation mode yet so why risk a likely coin flip(at best)?
