I have heard that the intelligentroutingd process also has something to do with the Xcode app, but I haven’t found any useful fixes. From my experience, there are some general solutions used to deal with these loads of strange programs on Mac. If you’re interested in them, you can have a try:
Completely uninstall Xcode from your Mac
This way only works fine for the users who install Xcode, if you haven’t installed this app, skip this method directly.
Open Finder > Applications > Xcode > Right-click it to select Move to Trash, then Xcode will be moved to Mac Trash. After this, you ought to move its associated files including caches, preferences, junk, packages, plist files, etc. from your Mac, which are stored in different directories or folders in Finder, requiring you to find them one by one whose names contain “Xcode” character.
If you tire of this uninstall mission, give iBoysoft MagicMenu a chance which lists all associated files of the app that you want to uninstall so that you can remove all unwanted files from your Mac along with the uninstall. This helps a lot in addressing the strange “intelligentroutingd” process, you can check if it comes out after Xcode is removed from your computer.

Update macOS or reinstall macOS
Some users have mentioned that this process happens due to the OS you’re running, which might be the beta version or a deficit. Facing this, the macOS update or macOS reinstall is recommended here. Remember to back up your machine before the macOS modification in case data loss happens due to any accident.
