This actually ended up breaking the Come Fly With Me quest by causing a necessary NPC to run outdoors, which caused a bug that made him relocate to Novac, rendering the quest incompletable. This means that sometimes when you enter any random room, the game will act like you are in combat and NPCs that you need to talk to will flee from you. The problem with this is that the game doesn’t like to end the “combat” state unless you kill all of your enemies. The most obvious issue is the fact that the easiest way to deal with combat encounters peacefully is to run away. While it is possible to complete Fallout: New Vegas as a pacifist due to the gameplay variety written into the narrative, the game’s engine does not make this easy. However, narrative is only one half of the equation. The narrative has plenty of options at each stage, and while not all of them are peaceful, there are plenty of options to make speech checks, hack terminals, or otherwise solve problems without fighting. This impulse to ask whether it would be possible to add a speech-based solution to any given quest shapes the design ethos of the game. Avellone, who is credited at the end of the game (if you have a certain perk) with the quote “Can I make a speech check here? Because I really want to make a speech check.” Fallout: New Vegas in particular owes a lot to the influence of lead writer Chris Avellone. Every choice that the player can make, including peaceful choices, has to be written in by quest designers. In game writing, narrative defines player choice in many ways. Partly, this has to do with the writing of the game.

I did the NCR path, since Independent is a little too easy to complete peacefully (since you can choose to just ignore all the minor factions if you want). Both the Legion path and the House path require, at minimum, that the Brotherhood of Steel be destroyed, but the NCR and Independent endings can be completed peacefully. It is worth noting that not all endings can be completed non-violently. The narrative of Fallout: New Vegas is unique in that it lets you resolve most of the main quest options without bloodshed and even lets you talk down the end boss Legate Lanius if you have a maxed out speech skill.

It is impossible to complete a pacifist run using these rules in any of the other Fallout games.
