This is a question that keeps cropping up, and I think I haven't been
answering/understanding the question correctly.

Firstly, LightDM does not have provide a GUI, so does not have any
a11y requirements that I can tell.  The greeter, which is basically an
X application (or a group of X applications if running a session) is
the part that would need a11y support.  This is much the same as
PolicyKit, where the core PolicyKit does not require a11y, but
PolicyKit-GNOME (or as implemented in GNOME Shell now) does.

If we look at the LightDM repository there is an example GTK greeter.
This uses GTK, so it has ATK support.  But I think the point you are
making that I was missing is there is nothing that starts
at-spi-registryd?  So even though the greeter has ATK support, it will
not do anything?
