There are template files available for each result layout. There are no options to achieve this unfortunately, the only possible way is to edit these result template files.
You can find them in the ajax-search-pro/includes/views/results/ folder. If you check these files, each one holds a commented part on the beginning explaining a few things.
It might be possible to add the missing HTML code to the corresponding result template. I've implemented this new templating system for these cases, however it's up to the user to edit them to his needs.
If you have any questions I gladly answer if I can, but I honestly don't know what code should you add/remove to have the star rating integrated with the results.Best,
