I'd talk about it.

I do think it was rather manipulative of you (even if done unconsciously) to ask your T if she wanted to save you. She's told you already that she won't play that game with you, but she's also already told you that she does care about you. Anyone who cares wishes that the person they care about hadn't gone through horrible things - but there really is nothing that they can do about it except to try to help you in the moment. Which is exactly a T's job.

What she was was rather insensitive, but unfortunately she probably didn't have the time to really think through what she would say because if she simply said yes or no then you would have also had a huge reaction. It sounds like she was trying to explain why she wouldn't have been thinking about wanting to save you - because it was in the past and she can't change the past.
