You can shrink most kinds of partitions (including ext4), and then
shrink the logical volumes (in this order). It's not as convenient as
growing the LVs since the partitions must not be mounted and shrinking
can be somewhat slow if data needs to be shuffled around, but it's possible.

As always, there's a small risk of data loss, so better have a backup of
important data.
