I thought Shor's algorithm could attack ECC too and the lattice crypto with the sci-fi crystal names (Kyber and Dilithium) was the response?

If I go to https://www.google.com using Chrome and Inspect > Security, I see it is using X25519Kyber768Draft00 for key exchange. X25519 is definitely ECC and and Kyber is being used for key encapsulation (per a quick google). I don't know to what extent it can be used independently vs it's new so they are layering it up until it has earned the right to stand on its own.

It's new so they are layering it up. At https://pq.cloudflareresearch.com/ you can also see if your browser supports X25519MLKEM768, the X25519Kyber512Draft00 and X25519Kyber768Draft00 variants are deprecated ('obsolete'?)
