On the other hand, I can’t remember Banks ever suggesting that organics in the Culture would want to die after a thousand years, only that if they wanted to die they would be able to. I don’t think the later is incompatible with anti-deathism—is Lazarus Long a deathist, after all?
I don’t recall seeing any people who are supposed to be older than a thousand years without mechanics like cryostorage/scanning; if you present a world in which pretty much everyone does want to die after a trivial time period, you’re presenting a deathist world and you may well hold deathist views.
EDIT: On the gripping hand, there’s also a substantial bit of business in the Culture about subliming.

About not subliming, specifically.
Such a character appears in the latest Culture novel, “The Hydrogen Sonata”. But he is stated to be extremely unusual.
IIRC, most inchoate Minds sublime during construction, but I could be wrong about that.
