Addressing the issue of filesystem use typically involves searching and summing file sizes (du).  The first step to addressing filesystem use issues is probably archiving or deleting unnecessary data, which isn't affected by LVM.  Beyond that, users might choose to address such an issue by re-sizing the filesystem, which is possible with LVM but generally difficult or impossible without it. Or they might choose to reinstall with different filesystem allocations and restore data from backup, which also isn't affected by LVM.

lsblk is magic, when you have RAID, encryption, LVM, ...
