I'm 95% sure the Lich won't die because the Lich is the main plot of the series and they have at least 2 more seasons like you said.

The tragedy, I'm sure, someone will die... I'm sure none of the main characters (Finn, Jake, Peebles, Marcy, Ice King) will die but with Flame Princess?

Killing Flame Princess would sure put forth another milestone in the show overall.
