Looking at 3D-prints might be a solution.

I was very sceptical too, but ordering some miniatures that were printed apparently using a resin printer (I am not into 3D-printing myself), they had no print lines, they were very clean and crisp. Admittedly the smaller the mini is, the less crispy details become. But not so much as to being useless, imho at least.
Or if you don't mind a little bit of bendy plastic look for D&D's Nolzur's Marvelous Unpainted Miniatures.
It also might be helpful to look for "Tabaxi" miniatures ...
