Think of it this way. You're the umpire in this sitch and BR heads to first after you tell her to - the rest of the runners advance - because you essentially told them to. And F2 inadvertently tags R1 before she crosses the plate. Are you going to rule her out once you fix the count? Of course not - and coaches would crucify you if you did.
Awarding the stolen base is equally wrong.
And you can explain it to the offensive coach that way if you need to.
Calling ball 4 erroneously put BOTH sides in jeopardy - erase the jeopardy and put the runners back.
Now ... an aside. What exactly did the umpire do to prompt the batter to go to first? Point? (Yuck). "Take your base." (Equally yuck).
