Am I missing something?

I've got no specific rule violation on the coach (or the players in this example) unless I felt someone was doing something to try and make the pitcher commit an illegal pitch.

I have never had a problem with the defense yelling "SWING" or "SWING BATTER", as long as they are not yelling things to make the batter think she has to step out (like "HEADS UP" or "BALL IN" on two fields that are close together and have foul balls constantly coming across.)

When it's getting extreme, I will normalling say in passing to the offender(s) something like, "That's pretty bush league. I usually only see it done at {insert po-dunk local town name}." They usually stops when they realize it truly is bush league and yields very little results.

If a pitcher is broadcasting her pitches during her delivery, then she should be mad at her pitching coach, not the opposing coach who notices it.
