You should remove any reference to LEGO from the website and the examples. LEGO is extremely protective of its brand (similar to / worse than
Nintendo) and does not want third parties using its name, because it is concerned that LEGO could become a generic term which could put its trademark at risk.
I'm willing to die on the hill that lego already is a commonplace word, but I can't argue that they've held on to the LEGO trademark for pretty long. Though, I'd say Nintendo is a lot worse than LEGO, and I've never heard LEGO do the frankly insane crap that Nintendo has.
They actually sued a lego youtuber (or threatened to sue - unsure) for using a lego brick in his logo.
this lead to him creating a new word for lego bricks "Klemmbausteine" which means "clamping building bricks".
