Looks like you need to shrink lvm a bit. EFI needs a partition
formatted to one of the FAT family filesystems, with no additional
software needed to access it, so no encryption or LVM. The size
recommendation for Linux is 1GB minimum. It's generally advised to
keep it near the beginning of large discs.
You have Boot partition and EFI partition mixed up. They are different
things.
EFI partition have to be formatted to FAT32, but its safe and sufficient
size could be even 100MB, because only UEFI executable binaries go there.
Boot partition, on the other hand, have to be big enough to hold a few
kernel and initrd binary files for at least 2 kernel updates and
bootloader (i.e. grub) binaries.
All of them in total could reach 1GB in size if you neglect cleaning up
old kernels after updates.
