Wouldn't take her in 12u because of the limitations you mentioned. Two things.
1. Maybe coach already had a girl or two on the team that were limited to only a position or two, it's fine having one girl that can only play first or only pitch, but having three...that's a problem
2. At 12u you want as much playing time as possible. Playing for a C team or rec will result in more playing time and more chances to improve.
If you/she wants improvement, address the weaknesses head on. Sounds like she's a decent pitcher. Cut down on pitching practice to work on other areas if practice time is limited.
Also, 30s seems real real real slow for 12u B. Around here that is closer to rec ball.
