0megaDS, I finished this quest last night and I didn't need to defeat the enemies that killed those Paladins. My current character was a pacifist playthrough, I am level 25, I have Medicine, Science, Barter, and Speech maxed, and Repair at 80. SPECIAL: S:2, P:5, E:3, C:10, I:8, A:4, L:10. Traits: Good Natured
I gathered the holotapes because I got past all the enemies there, with dialogue options that remove them, and while searching for the parts in the Vaults, my companion dealt with the enemies and I found the parts.
At Black Mountain, I repaired Rhonda and the Mutants there were not hostile anymore. I used a Stealth Boy and snuck past them all on the way up the mountain, repaired the robot, avoiding all combat.
