As you know, Colorado, Cleveland, Boston, and Arizona are up 2-0 and if all 4 sweep, this could be the shortest games for both league for LCS in history. But my question is, when was the last time that all 4 teams sweep their opponent at the same time?

Considering the LDS started in 1995 (1994 was cancelled), it's not that much of a stretch.

Although I hope the Angels are the only ones that break up the no-nos! :)

ya i knew that

It has never happened before. The most teams to sweep in the first round of the playoffs is 2 on seven different occasions. It hasn't had a chance to happen that many times because they didn't start having division series until 1995. (There was also a division series in 1981 because of a strike shortened season).
