When it comes to recruiting setters, college coaches tend to be more deliberate in their efforts and slower in the process; at least it is not as slow as liberos (who are last), but setters do fall behind the OH's and MB's.
It makes sense all the NCAA D3's want her because of her outstanding grades (she will be admitted and receive significant scholarship supports), in addition to her setting skills.
During this time frame, the NCAA DI programs are all crazy busy with recruiting and team training (remember that every DI program runs an "off season" which starts the first day of winter semester and goes until Finals week of winter semester for volleyball training), so coaches can be slow with communicating, especially lower DI's which don't enjoy the staffing support they should (when compared to mid and upper level DI's).
Any college coach worth their smart phone can see that your daughter's team is patching holes by moving players around, and if they can't see that, then you would not want your PSA playing for them anyways.
Focus on what you can control right now - Her effort/ability and the outreach/communication to collegiate programs.
Don't let her lose her playing focus; if she has 5 liberos on the court then she needs to find a way to make them competitive hitters because this is the job a setter. She may not have the perfect roster, but she can still make the perfect set to the best option of her attackers. Staying positive, working hard, being supportive of her team mates and not getting frustrated will speak volumes to observing coaches.
Expand your outreach efforts; you can never have enough college coaches coming to watch. What about DII? Division II is a great competitive level, and you can package out scholarships so her great academics can be combined with an athletic scholarship - I would be stunned if she would not have any number of full scholarship packages waiting for her at the DII level.
Expand your DI list; include many low DI's, many mid DI's and a few upper DI's - The worst thing they can do is not respond, the best thing they can do is come watch and be impressed - Only good things can happen when you expand your outreach.
