Those lists scarcely mention the alignments of any of those deities, and the descriptions of most of the more obscure gods don't seem to make mention of alignment in many cases either, except when they are at least big enough to have their own wikipedia article.

The best match I'm seeing just by perusing the lists is Karaan, a chaotic evil god of beasts and lycanthropes from the Book of Vile Darkness. The description in BoVD describes him as an entity of savage lust and wanton destruction, representing the dark side of nature and being enemy to Obad-Hai and Ehlonna. His followers are primarily beasts, and those that aren't tend towards behaving as though they were.
