Well what version of K-Lite are you using? The recent versions (2.1 is current) comes with an "auto-search more" option which will help in your search.
However what you are talking about, I don't think it exists. You're saying that there is a program which can search all the servers and find about 100 of the same file from different users - that's not really possible or easy. A program like that would have to scan all the servers and user files quickly as well as thoroughly in order to give you results like this. And what if there just aren't that many people with the file?
The only similar thing that I am aware of that even comes close to what you are saying is "Speed Up" and the auto search more option. Speed Up goes through every file you are downloading and automatically makes each one search for more users that have the same download, thus helping to improve the speed of your download by adding more users from who you are downloading from.
Sorry if that doesn't help, but I have no knowledge of an additional program other than the ones that come with K-Lite.
There is however a registry key you can download that will make your files unlistable, but that's something else.
