I don't know why Toyota doesn't have a Battery Saver relay to prevent this problem, or some way to use the traction battery to give the 12v battery a boost...

That makes no sense! Even my '02 Trailblazer times out after 20 min and automatically shuts off all lights interior and exterior if a door or the rear liftgate isn't closed all the way. All done in the body control module.
