You must have a very restrictive definition of grognard games. There are hundreds of wargames out there that would not qualify as perfect information. For instance, anything made by Columbia Games. If you study them mathematically, many of those games are actually quite a bit simpler than chess or go, because despite the large number of pieces, turn limits, order limits and very limited setup options will shrink the decision space in a major way. Those games are also easier to solve because, often to provide a light semblance to how history actually turned out, the rules are set up so that entire avenues of approach are restricted. So why are AIs worse? because when you make a videogame, getting the hardest AI possible is not really a selling point. We worry instead about not taking too much time, or, in case of a mobile game, not eating the processor alive. Those limits make entire sets of approaches to AI unworkable altogether. If a machine was allowed to think as long as the human does, and we had a reason to actually built said AI, you'd see humans losing a whole lot in wargames. You'd get a similar thing in Euros too, as entire avenues of playing just go away because they are mathematically inferior.
