In case this isn't bait, they brought up Hitler and the Holocaust because another name for the Holocaust was "The Final Solution", specifically to what anti-semites (like the nazis) call "The Jewish Problem," their words not mine pls don't ban.
So in this case, the priestess is just saying shit in her world, but to us, it comes off as a reference to one of the most well-known genocides in history. Which I imagine was a way to slightly manipulate players into seeking a more peaceful solution, though the violent option still very much exists.
Now, this could all just be me talking out my ass and none of it was in the base game, but I'm pretty sure ArzorX and the others are trying to run a respectable translation and keep it as close to base as possible. So, somehow I doubt it was just done for shits n giggles.
