The manual command line install page is Install /e/OS on a Google Pixel 7 - “panther”.
I guess that a brief read through it should help to see where you are in the install process.
Notice how part of your error message displays here as a link … which points to a download of recovery-IMG-e-3.0.4-t-20250709507786-official-panther.zip
Next you report “Downloading pixel-7-rom.zip” which will be the main ROM.
Notice the eos installer is installing Android 13 (T) official and not a community build.
