    If there is fragmentation in some of the indexes being used in a multi-table join query, would that cause TEMPDB to grow?

    You're experiencing heavy tempdb usage during execution of a query. Rewriting the query may reduce or even eliminate tempdb usage: the execution plan (actual, not estimated) for the query is the first place to look for potential improvements. If you can post an actual execution plan here - as a .sqlplan file attachment - folks will provide you with suggestions for improvement.
