I agree with Zaniel's take.

I would also say, yes, this is a plot hole. Dawntrail has quite a few of them. It's really more like a story with a sewer, and its plot holes are there by design like manholes. We keep going into them, hoping to find the Teenage Mutant Ninja Turtles and Master Splinter. Only, there is no Green Ooze, so we just keep stepping in shit.

Some things to consider about the two Otises:

- Robo Otis may not necessarily have the entirety of original Otis's souls or memories. While he is 400 years+ old via his robot body, since he was experimented on with having his soul diced up and inserted into a robot, it may be possible that some of the real him DID make it to Living Memory, not just a copy. It's not like we delved into his entire life's story in the half a dozen or so quests we met and watched him die.

- Living Memory Otis gets struck with severe PTSD just by acting in the play. Even if he's just a copy, we should probably look at the word copy and think of it more like clone. Then we gotta think... if you were to be cloned, would it be moral for you to kill your clone just for existing?

- It's been a few weeks now, and I haven't reviewed any dialogue, but I was pretty sure there was a mention somewhere in Living Memory about how certain Endless were given simulated personas of people important to them that weren't naturally in Living Memory as real people yet. Is it not possible then, that LM-Otis is one of these simulated personas? The PTSD would indicate otherwise, but Living Memory's whole schtick is making everything feel as real as possible for The Endless.

Only other thing talking specifically about living aether makes me think about is Valigarmandar's attacks. Even after 80 years and then even after its death, the places where it clawed and rained down attacks are burning with, "living aether." Some what surprised that we didn't go on a Valigarmandar living aether collectathon to see if it could sustain The Endless. Lmao, maybe that will be our post patch method for reactivating Living Memory (nah we probably won't).
