Are you looking for commands like lvremove and pvremove?
I'd already looked at those.
lvremove takes an LV identifier as argument, but since the cloned
partition has the same id as the original, and the original is still in
use on the active system, it won't let me remove it:
$ sudo lvremove -t -f fedora_localhost-live/swap
TEST MODE: Metadata will NOT be updated and volumes will not be (de)activated.

pvremove gives the same error as before:

I don't know why it's complaining about /dev/sde. There is no such
device on my system:

/dev/sda is the original (source) disk and /dev/sdc the new (cloned)
disk. Some partition UUIDs on /dev/sdc have been changed using gparted,
but it refuses to touch /dev/sdc3 which thus has the same UUID as the
original /dev/sda3. Ignore the temporary mount points for these.
For completeness, here are the current LV and PV listings:
