This is what I'd try.  Some part of the installer is probably scanning 
for stuff, getting confused by seeing this LVM setup, and refusing to 
erase the partition table and/or LVM metadata.  If nothing else, you can 
then test your "restore all non-OS data from backups" procedure this 
way, which is always a useful thing to do.
