EE are NOT a breed, they are a landrace or mix. EE *by definition* do not always lay blue or green. That's literally why Ameraucanas exist. BUT. They do have a certain expectations of traits still, like how a CX is not a breed or ISA browns are not a breed, but they still have identifiable traits. You can't just throw anything together and get an EE because of that expectation of traits.
In general an EE flock has (irregularly) blue/green eggs, muffs, green legs and peacombs. Many hatchery EEs do not lay blue or green eggs and may not even have muffs or beards - a major complaint when buying them by the uninitiated who expect a guarantee of blue eggs and don't get it. So if your rooster DOES have all these traits I'd say it's fine because even when bred to a chicken without those traits they're likely to get at least some of them. If he does NOT, it gets more iffy. If you have an "EE" with brown egg genes, no muffs, no beard, and you breed it to something else that has no muffs, no blue eggs, etc... Would you be happy to buy that offspring as an "easter egger"?
In general, the easy way of handling this is to have empathy. I think of it like this; would I be happy to have bought these birds from someone else? Would they fulfil my expectations of what those birds are supposed to be enough for me to not be mad? If yes then it's OK to sell them.
My concern here mostly lies in your roo. Your EE rooster may or may not hand down blue egg genes to the welsummers you want olive eggers from, which means the offspring might lay some very dull brown eggs and not lay olive at all. The easiest way to test this would be hatch a large batch of brown/white eggs from him. Blue is dominant, so if any of them come out laying brown/white he only has at most one copy of the gene to hand down. If NONE of them come out blue/green, chances are good he carries NO copies of the gene and that would not be a bird I'd use to breed for sale without full disclosure.
