- Gith know more about Illithids than most other races.
- LZ is an ordinary foot soldier. She has probably learned the history or their people (enslavement by Illithids, saved by Gith), that Illithids have strong mental powers and they infect people with tadpoles to reproduce.
- She may have heard that there is a cure, but she knows no details.
Now comes the problem:
Gith would kill any infected person at once (including a food soldier like LZ) unless this person is really importent to them.
At this point of the game we are just travellers or a low ranking Gith.
So cutting heads off is the only "therapy" they would give you.
Lae’zel isn't even a foot soldier yet, shes a trainee
