I guess they have their own fork of it?
Upstream hasn’t seen a new release, nor any commits, since 2015: https://lilo.joonet.de/
ETA: It is also my understanding that LILO fundamentally does not support reading filesystems, while Canonical want to keep SquashFS, among others. Adding support for that to LILO, along with whatever other features are missing, would likely be a major undertaking
Development stopped not because LILO didn’t need any changes, but because of its limitations (source):
Also, I dunno what your position is on this, but it is amusing to see calls for Canonical to replace GPL licensed software, with something with a more lenient license (BSD-3-clause). Normally that would cause outrage around here
