“the kesef mishna never meant that everything is called kla ilan, rather everything that color is nichlal in DINIM the gemara says for kal ilan.”

That would seem to be a rather forced reading of ??? ???? ???? ???? ??? ???? ???? ????? ??? ??? ?????? .

Ant the gemara in menachos is only muchach that kala ilan is a specific thing if you make the hanacha that murex trunculus is not kala ilan. Why can’t it be that there are three levels: Techeiles, Kala Ilan (which would be any “perfect” imitation of techeiles), and then everything else. And correct me if I’m wrong but I think the nimulei yosef did not say “plant indigo”, he just said indigo. And anyway the fact that the rishonim don’t mention murex trunculus as part of kala ilan is very reasonable considering they didn’t know of any blue dye from it.
