One thing here doesn't seem right. I thought the whole thread that this was about them negotiating down how much the executor of a deceased estate would pay to one hospital making claims against it. But the thread included things like: "She had been afraid of being sent to collections and asked why we wouldn’t just take their counter-offer", which suggests a (mis)understanding that it is a personal debt of the sister's.
This suggests an 'AI can't see gorillas' problem here in that, during an AI-human interaction, identification of relevant big-picture context that a human advisor could have helped with is also missed.
Depending on the state and their laws, spouses can be responsible for debt. Along with that, hospital could maybe not sue her but sue husband estate and those liabilities would trickle down onto shared assets so if they had a house, it's now got a lien attached to it.
