Is there a way to rotate the map referenced in the story map by 180 degrees?
One workaround you might want to try is to create a web scene from your map layers and embed that scene in your story map. You have much more control over the orientation/perspective of a scene than you do with a map. These two blog posts may be helpful if you want to try this:

Thanks for the info, Owen.
