I don't know if this has anything to do with WhyEm's DLC but before I even installed it, the NPCs never attacked me. But after installing it, every NPC seems to attack on sight, and it's not even lawmen. It's pedestrians with guns, even shopkeepers attack me. Does anyone have any tips on fixing this if this is going to be a persistent issue?

So I quite literally had this exact problem. but had to figure it out myself so i got you. rather than use the online unlocker mod (assuming you using both rdrOffline and online unlocker) go ahead and run WhyEm's with RDROffline instead making sure to disable online unlocker.Forgive me for the lack of commas my comma key is broken lol
