But if I hit the lock button on either door ever light on the dash and cabin lights all turn on while its pressed. The digital dash is more like a test mode because every light is on. I've replaced the LCM and all door switches. Checked all fuses and 5 pin relays so far.

Yep, there is a common ground at the right kick panel pnk/org wire that I would check here is the wiring diagrams so you can see. Check out the images (below). Let us know how it goes.

Okay, those grounds look good, it must be backfeeding through the driver door module which is causing the problem. Here is he door lock wiring so you can see how it works and how to change out the DDM. Check out the images (below). Please let us know what happens.
