Giving anyone reading a heads up: the "Targeting Hud Mod" (and also apparently "Berry Mentats") has the effect to highlight targets and may turn some NPCs hostile. (IE: Paladin Brandis and the robots at General Atomics Galleria) If you don't want them to be hostile, simply remove the "Targeting HUD Mod" BEFORE you get close enough to them. Or simply don't eat Berry Mentats.
I recorded a quick video to show an example:
