Hi Cameron
If you have downloaded the Shortlist code and self-hosted it, you may be able to include a Google Translate widget but I don't know the technical details of this. Here's an example I found that uses a self-hosted instance of the Story Map Series app template: The TransNet Story See the language switcher in the top right hand corner. This doesn't seem to translate the popups in the web map (although note that the Story Map Shortlist doesn't use standard popups for its place content).
The more common approach we've seen in bilingual story maps is to make two different versions of the app, and provide a control to let end users switch between them. For example here's a Shortlist example Shortlist Salzburg . Click the link in the top right to switch to the German language. And in this Story Map Journal, the authors customized it to add a cover page that presents a language choice: Sarayaku: in defense of territory
Here are some more examples from the Story Maps Gallery: Gallery | Story Maps
Perhaps others who have multiple language requirements or experience with these approaches can share their thoughts here too.
