Some of the cars are EXP models and there is nothing different than the cars GM have sold off at other auctions in the past,sold on Bill of sale only. Many cars are ones that GM purchased along the way of putting together the collection and should not have any issues with Titles.
I looked at the BJ list yesterday and only read one ad for the Green Hot Rod that was commissioned by Olds for its 100th anniversary, its has no title. No different from buying a race car that was built from the ground up for racing.
If someone had donated a car to the collection,that may be another story as to their right to resell it. i dont know how charity rules work with "Museums".
