A certain amount of semi-random stuff can, and should, certainly exist in any "open world" game.
If it's just the same options, dialog, interactions, etc. over-and-over what's the point of an open world? Seriously, what's the point? There isn't one. it's just a Marketing buzzword ticked off a list, no more.
While it's clearly HIGHLY impractical (to the point of essentially impossible) to make every encounter unique enough need to be to matter. If, as in many games, there are a small handful of unique encounters it's really more like random chance that players will even see them. As a rule-of-thumb I'd say around 20% need to be unique to encourage players to actively seek them out.
