This question is really really trust language-specific. I would need to know who the trustee is, whether it is a revocable or irrevocable trust, and what the terms are. If your grandmother is trustee and unable to speak or respond, then a guardianship can be set in place for her to run the trust which may help. If the lawyers are the duly appointed trustees, and not just the trustees agents, then it will be much harder to remove them absent showing a breach of fiduciary duty.
If you're willing to send the trust document over I can have a look. If you don't have a copy, you are entitled to one as a beneficiary of the trust. Make a request to the attorneys for one.
