Release from rehab with no care plan?

I've been trying to give advice to a loved one whose husband had a severe stroke a couple of months ago at 59. He's been in rehab, but the insurance coverage is ending. From what I know, the facility in FL has no care plan for him. They just told her he can't stay and has to go home. He can't transfer independently, and she works full-time.

I have been disabled from birth, so I know how Medicaid and long-term care works.

I wrote up some ideas, like telling them she can't safely take care of him and demanding a care plan, and she kinda got upset when my mom sent it to her. I've advised her to see an elder law attorney to see what she can do financially as to qualify him for Medicaid. From my experience and research, Medicaid is the only program that provides long-term care, whether in-home or in a facility. I also know he can only have 2K in assets, and she can keep ~130K, the house, and one vehicle.

But I do understand; they're telling her the only option is to take him home. It's like when people tell me I can do this or that in regards to working, and I want to respond "No, you just don't get it! The system won't let me without compromising access to disability services!"

I realize I can't convince her to be assertive or to seek help. I guess my main question is whether or not just releasing him with no care plan is even legal?

I worry about her health as two days ago a different loved one who has been caring for his spouse had a stroke. Thankfully, it only affected his speech and some recall, but their family is in crisis as well.
