Can't Locate a Single BSA file.

[2manymods]

Goal: Extract great Khan Outfit textures to change the logo and create new outfits with a different logo for a splinter group.
Problem: I can't find a single .bsa file anywhere in the Fallout NV data folder or anywhere else in the directory.

Things the internet has told me so far:
Look for meshes.bsa folder rather than just meshes. No such folder exists for me.
Use FOMM to open files from file explorer. Have FOMM, directory is empty.

Things I tried on my own:
Searching for *.bsa in file explorer for the whole directory.
Googling the hell out of it. Even tried Bing. I'm desperate.
Searched this forum and steam.

One Potentially Relevant Note:
I have one file in every folder in the data directory "folder managed by vortex". I started modding my games before I started making mods and even though i know how to manually install it seemed safer. I think I may have caused an issue with that, but the internet generally seems to say that's not causing this. I see content from mods I've uploaded but nothing base game.
From what I can tell there's no reason i shouldn't currently be editing files in gimp and setting them up for my mod. Yet hear I am with 0 access to base game assets.
Any help would be appreciated, I'm going slightly nuts here.

BSA are in the Data folder and should look like this
