Lauri said it very well, but I want to add my 2 cents as well.

I do not know about those being typical traits for liver colored German shepherds, as I have never met one, but combined, those are typical traits for a poorly bred German shepherd. Pale/yellow eyes, the liver color, and a red nose are all considered faults in the show ring.

As already stated, white German shepherd dogs are a whole 'nother story, but to answer your question, there are plenty of reputable breeders who produce long coated GSDs, or GSDs with other undesirable traits in the show ring. However, those breeders usually will not sell those pups as "breeding quality" dogs, and often you will find that breeders will charge less for a long coated puppy.
As for breeders who breed specifically FOR a fault, most will say that none of those breeders would be considered reputable. There is a difference between breeding two titled stock (or plush) coat GSDs that carry the long coat gene and getting long coat puppies and saying "well, he's a liver long coat and she's a liver long coat, and gosh darn it, they're awfully rare and pretty, so let's breed 'em!".
There is much more to the German shepherd dog than just color. A shy, fearful, "soft" German shepherd is not a good representation of the breed, and in my opinion, neither is a GSD that does not look like a GSD should. While there's nothing wrong with having a color preference (I love the darker colored dogs myself), a breeder intentionally and specifically breeding for faults is not my cup of tea. If you have your heart set on a liver, I suggest you look into reputable breeders who may have had occasional liver colored dogs pop up in their litters, and talk to them, or, of course, find one from a shelter or rescue.
