I'm dangerously close to running out of space for my VMs on local-lvm, but noticed I have a lot of free space in my local storage where I only have a dozen ISOs stored.

Can anybody help me figure out how I'd go about shrinking the local storage so I can extend my local-lvm?

From the comment:

This is how I do it:

boot into gparted (make bootable usb https://gparted.org/liveusb.php)

open terminal

run lvdisplay to check the proxmox root and data lv name and path
sudo lvdisplay

resize the root lv (choose size, no curly brackets)
sudo lvreduce --resizefs -L {size}G /dev/pve/root

resize the data lv to use all available space
sudo lvresize -l +100%FREE /dev/pve/data

reboot into proxmox
pray

I do not suggest doing this. Just add another disk.
