13/9 7/2, which I believe very few humans would play

I believe less humans would make that play than a few.

Is the bot playing correctly during the rollout?

The only way to ever really be sure of this question is to log the rollouts which you can do with GNU and then go through them game by game to see what is happening. A common thing I do is go through the immediate sequence to make sure the bot is playing the moves I think should be played (temperature map). I would trust the bot's play as much as I ever do here.

I would have played 13/4 here as the price you'd be paying now is more than what the going rate should be.
