You could do this by processing your index twice, in different modes.

In the TOC, you would process the index and generate a TOC heading for
each new initial letter.  The page number would be an FO forward
reference to some deterministic identifier (like idx-a, say).

Then, when you process the index per se, you would generate a marker for
the first entry of each letter using that same identifier.  The FO
formatter will backfill the page number, just as it does for chapter
headings.
