if strassa really has been running fsu over does this mean:

A. he expexts fsu to have a real hand here due to the frequency of his laydowns, and all that hes going to get to fold here is maybe an oddly played flush draw, and thus he is NOT bluffing

OR

B. he expects fsu to be calling down light because of his increased aggression, and that he can push fsu off of his weak two pair

How to determine this is beyond me, and the case for raising the river hangs on which of the two it is imo

I would tend to like a raise at some point before the river, most likely the turn, but i understand you think he has air and want to let him bluff. Once he continues to fire this way i think you can only cold call the river as he is either bluffing or has a monster, he is VERY unlikely to simply have the case A no kicker.
