I hope you won't be offended when I say you are reading too much into this. T probably feels that he can't advise you to sue, because that would be undue influence. Ts have to be very careful they don't end up running their patient's lives, even though some patients would like nothing better!

So he has told you, in as neutral fashion as possible, that you would be morally justified in suing. Whether you'd have any chance in court... Well, he's not a lawyer, is he?
