From what I can tell this is meant to be a "Your not supposed to be fighting them right now" kinda encounter.. now I can tell you I have beaten it a few times myself its a hard encounter if you don't know what your doing but not impossible. The game even tells you like 4 times "You really shouldnt pick this fight right now"
Also as for the "cure" itself as far as we know a githyanki cure called "purification" could just be decapitation as far as we know.. she is not an expert its even possible to pick on the fact she dosent really know what the cure is in the grove.
The Githyanki are NOT the main plot they are ONE path now true if you wanna experience all of the stories the game has your gonna have to deal with em at some point or another but you don't need to fight you can just talk your way out of a fight. Possibly killing them now will change some things when you go to the crèche specially from what we know will happen theyre with the datamined content.
Also keep in mind BECAUSE its EA you are limited to lvl 4 when full game release you will most likely be able to hit lvl 5 or 6 depending on how you play so the encounter will be much easier.
