Alright.

I should note that there's a bit of a contextual problem with the Tikali as from the setting they migrated from the Tikali's enemies were a nebulous god-like force in the galaxy that nearly wiped them out in a cataclysmic event as collateral damage ten millennia before present.  Over time their kind (The Silent Imperium affiliates, anyhow) developed to learn more of those beings and actually gain progressively more 'purpose' in their grand mission to basically wipe out what they viewed as a tyrannical force on the galaxy.  They are one of the most advanced species in that galaxy but only match their enemies in FTL speed and nowhere else.  The universality of the god beings meant that they actually had a quite byzantine network of alliances and associations with the other civilizations of the galaxy and got wrapped up in "side missions" of many sorts along with making more enemies as the same god beings happen to be worshipped by a couple of the other civilizations in that galaxy, who would have guessed?

Here however it's just plain ol' genocide by a faction who technology the modern Tikali may actually be currently technologically superior to in some areas.  The timescale is also shorter so the Tikali are not as advanced as they would be from the setting they came from (though they still have stuff like dematerializers).  What I do wonder is if the Dominion would earlier on at least put efforts into trying to hunt down those in space craft.  Arrangements on such details i'll for you to decide but in general the Tikali pre-invasion were space faring for about 50-70 years before contact with the Dominion.  The Tikali even this early had fast FTL, which is why the last 2-3% or so don't get completely wiped out.  The severe bottleneck caused by the genocide likely has softened over the next 1-2.5 thousand years however which is why I believe the Tikali would actually be pretty diverse by modern day and not have universal conformity to the Grand Plan.  Two thousand years is a lot of time.
