Couldn't the DM say something like "the hook horror rears back and glares at you...in an instant it leaps through the air and attempts to tackle you. Roll a saving throwing on...dex...to see if you get knocked prone...you failed, you are knocked to the ground taking....10 dmg as it charges into your chest and sweeps at your legs as it lands on the ground..."
Something like that....just because it isn't a specific attack, can't you adapt and use narrative?
I pick up a rock and throw it at the minotaur's eye....roll dex to see if you hit your intended mark...you hit....roll to see dmg.....you do enough damage to blind the minotaur on the left side of his vision....I keep strafing to the left to stay out of the minotaur's site, attempting to dodge his oncoming attacks....the minotaur now has a -1 to hit chance as it flails around in pain and anger.
Or are all your fights in D&D...I attack...I roll...I hit....I roll...I did 8 dmg...your turn....
Could the DM do that? Of course they could.
A DM could also say that aliens beam down and start a break dance competition with the Minos. Might even be fun for one single incident or a certain type of D&D group, especially if that was the expectation for that DM. Doesn't mean it would make for a good game if someone is expecting to play by the rules.
The expectation for *this* DM (referring to the BG 3 AI DM) is that it will follow the rules for a consistent approach to the game and have faith that for all its negatives, 5e is the most balanced version of D&D yet with 6+ years of playtesting behind it. BG AI isn't DMing for one group, it's DMing for every group and its been advertised as trying to be faithful to the rules of 5e. So that's what we expect the DM to do.
