So I actually narrowed down the offending mod to Indistinguishable Billboards for Skyrim SE. Whenever I generate LOD with this one active it seems to cause Wyrmstooth to CTD. I don't know how that mod would interact with Wyrmstooth, but Is there any reason for that to happen? Also to further test this. I generate the LOD and ran the game without enabling the mods. It seems like whatever is causing it to CTD is in bto files for that world. I tested that by deleting the Objects folder and seeing if it CTD on me and it did not. I do not know enough about BTO files, or LOD in general, to really figure out what's going on though.
