Technically no, they haven't encountered him before.
The previous animated movies with Broly in it were not cannon. (as he was a character created outside of the universe that the manga/anime was based on)

But fans loved him so much, that Kale was created in his image (one of the first female saiyans who has a berserker-mode transformation that looks just like Broly's legendary transformation)

But that wasn't good enough, so now - we get the real Broly revamped specifically to be introduced into the actual DB universe.

Also, I'm kind of glad they waited until Goku and Vegeta could go Super Saiyan Blue bc it gives them a chance to show just how powerful Broly is.
