That's weird when I go into TM, I see the application and utilities folder.
I suppose you can try to manually copy the folder from your TM backup, provided its in your TM backup.
look for the backups folder on your external drive that you use for Time Machine and then open up the folder that has your machine name. There you'll see all of your backups, look for the the folder called latest and open that up and then navigate to applications->utilities.
If it isn't there then for some reason TM did not back it up, you can also manually check some of the older backups. Be sure that you don't have your application directory excluded. This is really the only plausible reason why you don't have it in your backup (both applications and everything within the application folder)
