You are asking this question on a wrong mailing list.

LVM2 of course does fully support online device shrink.

The other side of story is - there is no filesystem I'd know about which
would be supporting online shrinking.  The fact is - it's pretty hard
to do and there are not many people interested in this feature - so I'd
not expect it would be written i.e. for ext4 anytime soon
(Since you could easily do that offline).
