Well, one probably should rush for the gith patrol, but then notice how everybody that ran into them have gotten killed. Then notice what they did to those fists. Then notice that the dragon is gosh dang huge! Then send Laezel in to have a chat with them, preferably on her own with everybody else far, far behind. Then you run far enough away that after the Gith catch up and kill Laezel, they'll go back to their normal pattern of goofing around and you can resurrect her, sneak off, and plan to come back another day.

But I agree that it would be better if there was some more sensible way to realise that her solution wasn't as easy as it sounds.
