Thanks for the feedback, guys! I implemented IDropInListItemRenderer and got ahold of listData.owner. You are right, itemRendererToIndex(...) will get you the correct index.
The trouble now is how do I bind the result of itemRendererToIndex to a label inside the itemRenderer so that it automatically updates when the dataProvider is changed? You mentioned overriding updateDisplayList(), isn't that function related more to updating the styles?
