I've only seen one Leylandii root plate failure and that was in the
bad gales in 2007 and due to the soil being waterlogged, thus losing
it's cohesive strength. So I would have thought on well drained soils
it is windfirm.

I would say almost certainly! For some reason I have formed the view
that Leylandii are notably windfirm, although they shed canopy from
tight forks where those exist. I'm not sure that height in itself
makes a tree, even a Leylandii, unstable.
No I have no experience of an appeal.
