It sounds like you are right in regards to the BCM causing issues here...
It looks like your Single Wire GM Slow CAN is down, as all the non-critical stuff looks like they are not getting data.
(The Single Wire Slow CAN looks after the Radio, HVAC, Cluster, etc)....

The BCM serves as a gateway between the Slow and Fast Can buses, but to have a failure like that is kinda out there !!!!
I would be checking the obvious stuff first, any fuses related to the BCM, BCM wiring plugs, and any wiring mods you may have done that involve the Single Wire Slow Can bus (If any)....

But yeah, to just confirm, I too think you are on the right track with the idea that the BCM is causing the troubles here...

Hope this kinda helps you out ???
