They didn't create him. The entire point of the first link above is that they were trying to contact a being far above their own dimensional box. And most of the listed characters in ultipotence and omnipotence only have the feat of creating everything and being at the top of the totem pole. Mxyzptlk also isn't ultipotent given that there are many other beings at his own level or a few even above in the setting. In any case, why should Kami Tenchi be discriminated against simply because his origin isn't the western comics that you are familiar with?
