I think the reason the gender is non-specific is to make Frisk as much of a blank slate as possible. You have to work extremely hard to find any evidence at all of their personality (and even then it relies on speculation); the game deliberately tricks you into thinking you name Frisk at the start; they don't speak at all and have a non-specific appearance; and the narration is all in second person to make it seem personal. I reckon that Toby probably did have a gender in his head, he just didn't make it explicit in the game so that the audience could be wider
