Logical Volume and mounted volume are different

Hello fellow redditors. Normally I do not have much issue with extending volumes and such with logical volumes. However, I'm a bit perplexed by my findings on a system today.

The LV Size shows <58.00 GiB and the mounted file system is only 8GB. Thoughts? What is my pee brain missing?

lvm> pvs

PV VG Fmt Attr PSize PFree

/dev/sda2 rhel lvm2 a-- <59.00g 0

lvm> vgs

VG #PV #LV #SN Attr VSize VFree

rhel 1 2 0 wz--n- <59.00g 0

lvm> lvs

LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert

root rhel -wi-ao---- <58.00g

swap rhel -wi-ao---- 1.00g

lvm> exit

Exiting.

[root@SERVER1 ~]# mount | grep root

/dev/mapper/rhel-root on / type xfs (rw,relatime,seclabel,attr2,inode64,noquota)

[root@SERVER1 ~]# df -h | grep root

/dev/mapper/rhel-root 8.0G 7.2G 813M 91% /

How would one extend the FS when PFree is 0 and LFree is 0? can you tell xfs to only format 8GB of a 58GB volume?
