lol. I remember seeing LLLSDL go by when I originally saw the movie. The funny but is I had just written the internet draft for LLSD, so I was wondering g if someone on the writing staff had been following our work at Linden Lab. More likely it was a coincidence and all the L's meant "Laser."
As I pointed out to the OP on Mastodon, I very much believe that it was a reference to Lawrence Livermore Laboratory, where they filmed a big door, and the original laser sequence from the first TRON movie.
LLL also made an in-house video when they were filming the original movie - https://www.spyculture.com/dept-energy-invent-making-video/
