If a store actually delivers counterfeit bricks, returning them is not relevant. Bricklink stores rely heavily on their reputation, so anyone pulling a stunt like this would have to start over and over again.

> I could also imagine that you can buy china-manufactured parts that carry the lego logo.

It wouldn't gain the manufacturer anything, but cost them in terms of liability. It would also mean they can't sell bricks made with such moulds to any party which very much does not want get into a trademark dispute with the Lego Group. So it is very, very unlikely.

There are plenty of cowboys out there who produce sets which look way too much like Lego sets (boxes and all), and which violate the trademark by having logos which sort of look like the Lego logo if you squint, but bricks with the literal Lego logo on them would blow away any sort of defence based on plausible deniability.
