That might be a mistake that an AI would make, after finding so many other things on the 'net where it is misspelled that way.
The choice in the group's name would have been one person's mistake.? It may have carried over to all the articles too.? Heck, it's even possible that the AI wrote the article spelling it "LTspice", which the group's owner then edited to introduce that error.? It's possible that all individuals involved in that article never actually used LTspice.
