the reason for the T is that the contact was not player to player, but ball to player. A1 throws the ball at B1's head, you can't call a personal foul; T is your only option.
This is different because of the fact that A1 hasn't released the ball, and the intent is less than malicious. Personally, I'm likely to call an intentional personal if it actually happens as posted.
