Shouldn't this Lampent say "Oh my Arceus, Mom"

If they're using normal human language to communicate anyway, they might just use the term God to refer to Arceus, in an interchangeable sense. On that note, it would be reasonable for them to use the term "god" to refer to a single lesser deity like Dialga, and "gods" to refer to collective groups of them.
