my take on the tcho-tcho, to avoid the pygmy cannibal or orientalist of later authors, is to have them be an extinct culture being culturally appropriated
they were a strange other species of hominid or offshoot of humanity
perhaps they had a rich culture, but now the creeps imitating them and violating time and space to learn more about their cannibalistic rites and occult secrets (or an irresponsible Yithian left notes that were later copied) don’t care about that
some things in the Cthulhu Mythos should just be dead but that doesn’t mean the story ends with death
