I was able to open the images on my iPad. The image of the dash is consistent with all of the CAN Bus communication errors--the combination meter (dash display) does not know what to display. The DTC list from Leaf Spy is full of communication errors so it is likely all related to CAN Bus communication. I just suggested to try disconnecting the intelligent brake controller because it is a rare, but known issue on 2015--there is nothing in the DTC list to suggest that it is truly failed. I think you will need to get beyond the lock mode and ID discord errors before you can go very far troubleshooting (B2192, B2604, P1610, and P1611 in your Leaf Spy DTC list). Since the 12V battery is being discharged whenever you have anything powered, I suggest you connect an external charger to keep its voltage up to 13 or so while you are troubleshooting.
Your description of the car is interesting--insurance payout would normally be related to collision or comprehensive coverage and not mechanical or electrical failure. Perhaps the car was stolen, run completely dead, and then recovered. Another possibility, although unlikely, is a severe power surge during charging caused by nearby lightning strike (act of nature as far as insurance is concerned). I doubt that you can get it to accept any charge (L1/L2 or DCQC) without getting enough CAN Bus communication functional for the LBC (lithium battery controller inside the battery case) to communicate with the onboard charger and VCM (vehicle control module).
Can you search for service history using the VIN to get any clues (maybe even call the original selling dealer)? Also, there were a few times when I had to clear DTC's caused by public charger communication issues before being able to charge my 2015 at another station (either L2 or DCQC) so I will reiterate that the communication issues probably need to be solved before it will charge.
