I thought I read a post that questioned the existence of imaginary (complex numbers) and I was responding to that.

I was responding to the Header, which questioned the the existence of 'i'.

What sort of thing, if any, do you think Russell would call a "convenient non-fiction", or just a "non-fiction"?

I would imagine that he would think of the chair upon which he sat as a convenient non-fiction. A non-fiction would be an actual object, like a table, chair, tree, or person. And "convenient fictions" would be useful concepts that do not have physical instantiations. However, this is me guessing rather than finding anything in Russell regarding your question.
