You simply extract the entire kas_24aa.rim and kas_24aa_s.rim and pack those unmodified files into kas_24aa.mod before placing it into the tslpatchdata folder just as you would for 2da files etc.
Then you add this .mod file to the installed files, making sure that the "Replace" box is NOT checked. Generally in the file installation this box specifies whether or not TSLPatcher will skip the file if it finds one of the same name in the installation directory or replaces that old file. And since TSLPatcher does the file installation first before doing any modifications, this will make sure that the necessary .mod is always present when installing your mod. Any mod installed afterwards will then patch the files inside the .mod.
