As long as the ball clearly bounced off of (and was not bounced/tapped by ) A2, no backcourt violation - there is no team control during a throw-in and team control is not established until a player establishes control.

I am not sure what you mean by "bounced by A2" but if A2 tapped the ball into the backcourt it still would not be a backcourt violation. It would be no different than if A1's field goal attempt was unsuccessful and A2 while trying to gain control of the ball off of the rebound tapped the ball into the Team A's backcourt because he could not gain control of the ball and did not want B1 to gain control of the ball either.
