do "dmsetup table" and see if there is a mapping to the device you want to get rid of. If there is no mapping you may be able to exclude the device with a filter in /etc/lvm/lvm.conf or you may have to used the really dangerous commands to clear the data of the disk. Doing just about anything is going to be really dangerous and tricky given the device has duplicate uuids at the LV and PV level. There are ways to fix it, but most of those ways will either be exactly right, exactly wrong and you no longer have any data. I don't think fdisk will prevent you from removing the partitions, but you will need a reboot or manually delete the live partitions mappings to get them to disappear from the OS.
