My code:

add_filter( 'a_z_listing_item_indices', 'my_a_z_index_filter', 10, 3 );

function my_a_z_index_filter( $indices, $item, $item_type ) {
    // make sure we're filtering the right post type
    if ( 'page' === get_post_type( $item ) ) {
        // pull the title and get the first letter of the second word
        $full_name = explode( ' ', $item->post_title );

        // the last word is in the last element of $title_parts so check it is there
        $last_name = array_pop( $full_name );

        // ensure we actually found a last name
        if ( $last_name )  {
            // cut the first letter out for our index
            $index = substr( $last_name, 0, 1 );

            // set up a new empty array
            $indices = array();

            // only the first names are left in $full_name. Join them together again
            $first_names = join( ' ', $full_name );

            // Now put the last name first and separate with a comma+space from the first names
            $formatted_name = "{$first_names} {$last_name}";

            // add the new name associated with the item into the new array we created
            $indices[ $index ][] = array(
                'title' => $formatted_name,
                'item' => $item,
            );

            // return a new array with our new index letter instead of the
            // indices already discovered by the plugin
            return $indices;
        }
    }

    // if we get here we didn't override the indices so return
    // those already discovered.
    return $indices;
}
