Foul on Inbounds after Time-out

[golfdesigner]

Just want to refresh my memory.
Sit: A62-B57 both teams in bonus 1-1
B makes 3-pointer (now A62-B60), with 10-seconds left, after ball goes thru basket B immediately calls TO. After TO, A will inbounds under B's basket with right to run the endline. B wants to foul A as quickly as possible to send A to line for 1-1 hoping A misses or only makes 1; so a 3-pt at the buzzer can win or tie. B indicates they want to foul A during inbounds, while clock is still stopped.
Question: at what point do we have intentional foul, if at all? Penalty for intentional is 2-FT plus ball at spot nearest the foul.

Comments?
Thanks
