i choosing a computer to connect to an unlocked Pixel and install GOS.

does any identifier or info from the computer end up connected to the new phone & OS?

well I'm no expert at flashing but i see no reason why the computer used should leave any kind of identifying mark on the phone.

Use a PC you trust to flash GrapheneOS, i wouldn't use some random library PC or public Wi-Fi unless you have some specific threat model which demands this.
When your done flashing verify the installation using the attestation app if you have access to another smartphone, if not just verify the boot key hash.

Happy flashing!
