I imagine most of the Gith flavour text was designed with a Lae'zel origin playthrough in mind, although, there is some that is designed for the PC.
On the other hand, the game did offer a unique ending with a romanced Lae'zel... until they opened it up for everyone to get in the last patch.
Edit:
Shame they didn't offer that as a race option, would've made certain classes and dialogue options feel abit less strange.
Also could've added some character drama with Lae'zel too.
