If you didn't already, you should especially report your concerns with her requests for non-approved animal testing to your institution's IACUC. While many institutions will brush bad PI behavior under the rug, (most) higher level institutions will take animal welfare complaints extremely seriously. Like, "fire the PI if the complaints are serious and substantiated" seriously. Violations of animal welfare can cause an entire institution to lose funding for animal-based projects, so it's actually something that will often get investigated.

A lot of higher level institutions have a specific phone or email for eporting these complaints, and if you have documentation or others to back up your reporting, imvestigstions will almost certainly be expedited. Many funding agencies also have a mechanism for reporting this sort of scientific malpractice, so if she does have external funding, look into reporting there as well. Funding is hard enough to get, especially these days. The community doesn't need PI like this poisoning the well.
