For some plugins, yes. Plugins like DLS and EUP that run completely independently of LSPDFR don't require it to be loaded in order to work. However, things that require you to put them into the LSPDFR plugin folder like callout packs, LSPDFR+, etc obviously require it to be loaded in order to work. You do need RPH in order for any plugin to work by the way.

RE: GAME SHUTS OFF WHEN I PUT IN ADD-ON VEHICLES
Hi, I'm like 4 days late but you need a custom gameconfig in order for addon vehicles to work. You should also make sure that you're following the readme that usually comes with addon cars and adding the dlcpack to your dlclist.xml. I recommend using this: https://www.gta5-mods.com/misc/gta-5-gameconfig-300-cars
