Anyone out there have any experience with those irrevocable trusts?

An irrevocable Trust made 9 years ago by my sibling when mother signed a durable POA instead of a Medical POA my sister told her it was a medical POA but it was not, can she still get Medicaid? My mom cancelled her POA my sister had made but it was to late she had already took her $$ and moved her home and land 27 + acres & put it in an irrevocable Trust. My mother lost a law suit she had against my sister. Now at her age 99 she has more needs, she fell in 2015 had to have heart surgery and had hip replacement and can't walk and do a lot she did before and they have not helped her at all, saying she had $$ enough but she spent what little she had. They got a court order to sell her home giving my mother 4 weeks from March 6th to move her long lifetime belongings and selling her home and making her take all her furniture and personal things she had in the house out. I have helped her since 2009 and she is in an assisted living and I have been paying the difference in all she needs because all she gets is not even enough for the total price of the assist liv plus her AARP, Medicine drug plan & medicines the plan does NOT PAY. Plus her pull ups, pads, diapers, extra things over the counter & more. Will Medicaid help pay ins for hospital, medicines, incontinent supplies she can not afford. Nursing home also may be needed. I took care of her from 2009 thru 2015 when she fell and a few months later I fell & it was to hard to help her as I did. But I still do everyday. They devastated my mother and the courts do not see the true issues they lied and won. How can they do this to their mother?
