Can't deal with non-existing css files [#1721660]

I'm running the Tao theme. A number of css files are referenced in tao.info, but are not included in the theme folder. I'm not sure how to deal with this. Should I create the files and put them in the theme folder or remove the references in tao.info or is there something I can do that I won't forget about if I update the theme?
I get the following output in the "Asynchronous debug info:

I also have the list of tao css files not found in watchdog.
I'd appreciate any advice. Thanks
