<p>I think what the OP is getting at is, since a KKG can be both something elemental (Wood Release, Lava Release, etc.) as well as something non-elemental (Doujutsu, Shikotsumyaku, etc.), and since we know that a KKT is also something elemental (i.e Dust Release), then is it possible for there to be a non-elemtental KKT (a Doujutsu KKT)? Given the existence of elemental/non-elemntal jutsu in the "levels" below KKT (KKG) and above (KKM, in the form of Kaguya's and Hagaromo's doujutsu/Expansive TSB), I'm inclined to say that it is <i>possible</i>. But we don't have any proof of such thing in-universe and since KKT can be taught to someone with no relation to you (and KKG can't) and apparently KKM "operates by different rules than KKG and KKT" it may very well be the case that KKT is something Mu (or whoever) just made up and exists in its own category.
</p><p>As for the pseudo KKT thing, No, a non-pseudo KKT would just be a <i>real</i> KKT and a <i>real</i> KKT is combination of 3 basic natures, not 2 KKG. If that was the case, then that would mean that having 2 KKG is requirement for using KKT and thus Mu and Onoki would have them, but alas, they don't.
