Regardless of background, experience in working with the same material, specifically "6/4 titanium, shaped, thin-walled tubing" is the particular skills you need to repair your frame.

Litespeed may not be able to give you a more timely or personal response unless they have the frame in front of them and can see clearly what needs to be done.
It's Litespeed's name on the frame, they should be able to make good with it regardless what it needs; even if replacement frame at a significant discount.
For me that certainty is more important.
