The Batter of course is out.
The question then becomes did a retired player interfere with the play?
I am going to say no she did not as she was doing what she is supposed to do (run to 1st) when you hit the ball. She looks back saw she was out and stopped running. She is clearly in foul territory and did not intentionally interfere.
