My guess is no. My search led me to this:

Classification Using Nearest Neighbors

where you can see how you can use NN search for classification and:

You can use kNN search for other machine learning algorithms, such as:

-> density estimation

On this link one can find some nice theory on the topics.

PS - I am not sure that there is no such thing you are asking, but it exists, it is very well hidden(which means that not many people use it), thus it probably doesn't exist.
