Maybe my cartridge just hates her.
From my experience her dodge in OG2 indeed isn't that good, but give her dodge-boosting items and she should be fine. Again, keep near Bullet for relationship, make sure she's flying and don't be cheap with focus/alert, and remember pilots with leadership boost everybody's dodge when they're nearby (mothership pilots always have leadership).
But look on the good side! She gets +3 will every time she's hit! Girl's a masochist. No wonder she gets defensive support.
Also, how could you think Lamia
[spoiler]
was a mole after she self-destructs in her former masters?
And of course she isn't dead. You should know that nobody truly dies in a SRW game untill you're near the end. And mechas reduced to dust are also rebuilt as many times as needed untill the final showdown.
