ETH Zürich is up there high, particularly for computer science.
The LLM they were involved in last year (Apertus) still was a letdown.
As someone who actually went there, my impression is that Europe in general is complacent when it comes to computers, and any bright eyed student will get their motivation choked out of them in academia here.
If you want to do things with AI in Europe, you can have a bigger effect by working for a consulting company than being at a university. That's … not a good sitatution.
