What your question does not say is if the coach/trainer attended to just one of, or both of the team A players. If both were attended to, then both need to leave the game. The team captain/coach would then be allowed to choose who will take the free throws in replacement of A1, assuming she was attended to.

With all of that said, I would be making sure both players were actually attended to, and the coach/trainer didn't attend to one and just simple ask the other "Are you ok?"

You'll need some rules basis to back this up. If you beckon a coach, it doesn't matter if they attended to the player or not.
