If you use LVM on the whole disk rather than on the partition, then the 
limits become those of LVM rather than of the partitioning system you 
use. I don't happen to know the limits of Linux's LVM offhand, though.

That said, I wouldn't recommend using LVM without partitions, simply 
because there may be some poorly-written tool out there that ASSUMES 
every disk is partitioned and will do something bone-headed and damaging 
if it encounters a disk that uses raw LVM. Murphy's Law guarantees that 
you'll be the person to discover this behavior on your two 3 TB disks 
that hold your entire DVD collection that you've just finished 
transferring to disk.

Since Linux understands GPT just fine, there's no point in using LVM 
without partitions, even on a huge disk.
