My default address bar search is DDG, but need to fallback to google at times, and I keep my iPhone relatively google-free (Other than google voice).

Use !g at start or end of your query to query google https://duckduckgo.com/bang

Or, indeed, anywhere in your query. "test !g query" will search Google for "test query".
