Deliberate lane violations on free throw?

Team A is down. They need to miss the free throw and get the rebound to have a chance to tie or win the game. Team B doesn't want that to happen so they repeatedly violate on the free throw. The officials decide they are going to ignore B's violations so A's strategy might play out. Except B2 and B3 still violate by entering the lane too soon. The officials ignore the violation, and the rebound is caught by B2 or B3. The game ends, Team A loses its chance to tie or win the game because the officials ignored the violation. How should the officials have handled this situation?

If you go back and check my previous responses, my first choice is to continue to penalize the violations as they occur.

I can see the reasoning for ignoring the violation in the OP's play using the same reasoning as the interp play where we are instructed to ignore a defensive player intentionally stepping OOB to get a whistle to stop a fast break by the offense. However, the same "what-if" happens in that play - what if the offense misses their layup and the defense gets the rebound?
