As far as I know, you're not mistaken. That's also one of the major reasons I don't see the 732 Ravenloft entry date as in any way feasible. One could argue that neither Strahd nor Azalin have ever had any perfect ways of understanding what happens in other domains without actively seeking out that information. And one could argue that the Burning Peaks cluster was probably quite far from Darkon and Barovia. Those are at least decently convincing explanations.
But I'm still going to use the Vecna date as the keystone and eliminate 18 lich-years from Azalin's Oerth time. Does that create any Greyhawk inconsistencies, TwiceBorn Reborn? So far, nothing I've read in Greyhawk ever even mentions Azalin. Even online timelines never mention him. Would making him attack Innspa 18 years earlier really cause any Oerthian issue whatsoever? I would be really really really interested in hearing more about this.
Having reread the entries for Vecna and Kas in Domains of Dread, I can imagine them desperately lost in the Mists in 581 CY / 732 BC through 750 BC, catching fleeting glimpses of one another as each hunts the other down for what seems like an eternity through the fog - and perhaps pocket domains? - neither getting the upper hand or a chance to destroy the other. After tormenting the two like that for 18 years (perhaps a relatively short time span for a vampire and a demigod lich, but maddening all the same I'm sure when you're just going round and round in circles impotently with your most hated enemy so close, yet so far!), their respective rages building up, the Mists kick things up another notch by finally granting them adjacent domains. That 18-year hunt through limbo probably would have escaped the notice of Azalin, Strahd, and their agents.
If you're looking for a very cool pocket domain (with a connection to Azalin/Darkon and Greyhawk), check this out:

Sorry for the tangent...
As far as your question is concerned, no, Azalin is never mentioned in any official Greyhawk sources. Having just skimmed through the key sections of the Living Greyhawk Gazetteer, The Marklands, and Ivid the Undying -- the most relevant and detailed sources covering the histories of Innspa and Knurl - making Azalin attack Innspa 18 years earlier does not appear to create any inconsistencies with the timeline of Greyhawk/Oerth. Seems like Innspa was in a prime location to be caught in the middle of decades long border skirmishing between Nyrond and the Great Kingdom of Aerdy, the latter aided by its northern vassals in North Province and the Bone March (Knurl is part of the Bone March). Nyrond declared its independence from the Great Kingdom of Aerdy in 356 CY (think of Aerdy as a crumbling Roman Empire, or something along those lines).
Even if you have no intention of plunging deeper into the lore of Greyhawk, do yourself a favour and download Ivid the Undying:
https://www.acaeum.com/library/ividundying.pdf.
It was an official TSR product that was never published (save for excerpts in Dragon mag), and which TSR/WotC eventually released as a free download. Some fans formatted it to match the other books in the post-Greyhawk Wars supplement line, which, as far as I'm concerned, is some of the very best stuff ever written for D&D bar none. Although his work is controversial among Greyhawk fans - Carl Sargent's writing and the historical and political depth he infused into his work is awesome.
EDIT: Innspa was actually a city in what became the Prelacy of Almor around 437 CY, a buffer state between Nyrond and Aerdy, allied to Nyrond (i.e., another realm that broke away from Aerdy)... but that changes nothing where your purposes/needs are concerned.
EDIT 2: I'm curious as to why Azalin - who by 391 CY had "renounced his allegiance to the Malachite Throne" (i.e., Aerdy) - decided to march upon Innspa, which was more than 180 miles away from Knurl... perhaps because he feared that the devout of a clerical fief (dominated by followers of Hieroneous, LG god of chivalry, honour, justice, valour and daring) might try to take him down if he did not take them out first? That indeed seems to have been the case, given that extremely powerful 'mercenaries' came seeking revenge on Azalin in Knurl and were strong enough to send him fleeing for his unlife.
