Are they any different? Has this algorithm completely supplanted modern computer chess to the point that there's no more work on improving chess engines the old school way? No more "styles" that is?

Supposedly Fat Fritz has a more tactical style having been trained on human and possibly computer games. AlphaZero on the other hand learned from scratched by playing against itself, as did Leela. This gives the engine more of a positional style. They're both incomprehensibly strong though of course. The old school way is still going, as Stockfish is still a competitor.

Have any humans drawn it?

Is it though? They used TCEC openings, not all of which are objectively sound...

But every engine had the same opening set to deal with.

If the opening is dead lost at the level they're playing, Stockfish is going to collect wins it would not otherwise get.

Then the opponent wine and it is a push. No different than two draws.  One point apiece.

Yes there is a difference. If only sound openings are used, stockfish might not score any wins, only draws.
