Apollo was way bigger than the LHC, $200B (today's dollars) vs $7B. The engineering of the LHC is impressive, but a lot of it is scaling such as bigger semiconducting magnets. With Apollo everything was unknown, huge rockets, space suits, life support, space rendezvous, cameras, pens, even Tang.

Tang wasn't invented for the space program, it was merely a commercial food product they happened to find a use for. The Space Pen was inspired by the needs of the space program and was used in it, but wasn't a prerequisite for it.
