My guess would be that the motherboard has a chip inside that has a

flash image which expands it from the end of the disk on forward. That
would explain why it took over the tail end of the LVM partitioned off
space. There are probably no safeguards for the routine to check first
what is setup before going to town and doing its thing.
That's almost certainly what happened. There was undoubtedly a hidden
partition at the end of the disk, and that partition got wiped out when
the Linux installer was told to use the whole disk. Pressing the magic
button restored that hidden partition, overwriting the end of the LVM
in the process.
Simplest preventive measure is to leave that partition in place when
creating the LVM.
