And the Omnicron are a 100% robotic lifeform that has a computer serving as a brain.

Again, you can't have it both way, If Endless aren't alive, Omnicron aren't alive. Both are computer. Again, I agree by real world logic that the Endless aren't alive, but it not my fault if Coomputer are living being in lore.
The Omicrons were living beings who voluntarily uploaded their collective consciousness into machines. Then they got stuck in a rut of conquest and destruction until they were destroyed. They don't re-develop sentience until they're influenced by dynamis. So I would argue that they weren't really alive until the Endsinger meddled with them.

Which also brings up another point; the beings in Ultima Thule can exist independently of the Endsinger, while the projections in Living Memory fade out when their leynodes are shut down. A handful linger on for unfinished business, but they too disappear as soon as it's completed. They're automata.
