Anything that forces any kind of save is great against legendary creatures, making them use up all their legendary saves so the casters can jump in and wreck havoc. I had a battlemaster fighter halfling, and after action surging against a white dragon, I had managed to force five saving throws on it on my single turn alone.
It should be noted, that's due to how your DM chooses to use Legendary Resistance, rather than saving them for more significant effects. With a narrative ability designed to make the fight interesting, I wouldn't have used them like that. It's hardly universal.

The DM ran the dragon as it would be expected to react, and not by metagaming knowledge (saving them for some later worse attack by the players). The dragon didn't know our party composition, or what exact spells we used like the DM did. To be honest, if you metagamed the dragon's reactions for what you felt was more cinematic rather than how it would naturally react, I'd probably not be happy with your DM style.
In this particular example, we laid a trap for it, and I was the first to go. The dragon didn't know we had a wizard waiting in the wings. And the prideful (and stupid) dragon wasn't going to allow itself to be goaded into attacking a little halfling. So it used it's legendary resistance on my attacks.
