Why do I need a physical volume for LVM?

This is one of the reasons I prefer to have one big physical volume on the VMs that is separate from the /boot and other initial parts.

Can you reclaim hard drive space with LVM?

Reclaiming hard-drive space with LVM just scratches the surface of LVM capabilities. Most people, especially on the desktop, probably don’t need the more advanced features. However, LVM is there when the need arises, though it can get a bit complex to implement. BTRFS is the default filesystem, without LVM, starting with Fedora 33.

How does a LVM volume work in Fedora?

Physical volumes add available free space to the volume group. A typical Fedora install has one formatted boot partition, and the rest of the drive is a partition configured as an LVM physical volume. Out of this pool of available space, the volume group allocates one or more logical volumes.
