No....
The files are exactly as listed...
com.apple.logic.pro.cs
and
com.apple.logic10.plist
If you are sure they are not in your User library then either...
Logic pro X was iunstalled under a different User account....
Or...
Logic Pro X was not installed correctly.....
To double check... to make sure they are not on your system...
Download and install Find Any File from here (Its a free demo)
http://apps.tempel.org/FindAnyFile/
Then use that app to search for both those files...
If either of those files exist on your system disk, it will find them.. and then you can delete them manually yourself..
if FAF doesnt find them then LPX did not install correctly and you will need to delete the LPX app and reinstall via the Puchase tab in the Mac App Store
