Both Hraesvalgr and Nidhogg seem to believe that she's dead for good. Midgardsormr hasn't said anything one way or another on the topic, and he'd probably know best.

At any rate, I think it unlikely that Ratotskr will be making any kind of return, though it'd be an interesting plot twist if it turned out that all people of Ishgard could band together to summon her, or something.
I think, prior to Ratatoskr being killed, no First Brood had died. I'm not sure if anyone could call it one way or the other. Ultimately, I think it would be determined by what works for The Plot though.

Magic and all that. They don't gotta explain nothing to nobody.
