I use LVM wherever possible.

LOL ... i bite my tongue to not point out the obvious LVM problem :)
I've run Linux since 1995, starting with Slackware, old Redhat, and then Fedora.
I've used LVM since roughly 2001, including on laptops and workstations, on the servers for what was then a regional ISP, on the servers for an entire school district, and back in the day I used to manage high traffic NNTP servers for some of the smaller national ISPs.
I have LVM on spinning rust, on SSD, and on various virtual/SAN/cloud layers. For some volumes I interpose a layer of mdadm software RAID-1.
Among other things I currently run a public mail server and the primary TDE mirror which feeds all the other TDE mirrors as well as serving a portion of user traffic. Both of these systems handle a lot of disk IO and both use LVM.
I always upgrade in place - after extensive testing - rather than wipe and reinstall. Our systems have also been cross-graded in-place from Ubuntu to Debian to Devuan to Debian, and have been cross-arched from i386 to amd64 when the motherboards were upgraded.
LVM has saved me several times from bad sectors which would have required a wipe and reinstall without LVM.
LVM backup configuration has also magically saved me once from my own error when I mistakenly deleted the wrong logical volume.
I have never experienced any errors attributable to LVM.
YMMV.
Nevertheless, forewarned is forarmed, so I would like to hear more of the problems you have encountered with LVM. All that I have read over the years of LVM data loss has been mostly theoretical.
TIA,
