If you use the Chrome sync phrase, Google cannot access your passwords and thus they are not visible in the online password manager. Furthermore, if you delete passwords client side, i.e. from the password manager in Chrome, you are also deleting the passwords server side. This allows you to delete all passwords at the same time using the classic Ctrl-Shift-Canc.

This https://www.dropbox.com/s/s3tzbree2ddjnar/Screenshot%202020-... is the password manager I see in chrome, and I see no way to delete more than one at a time, or to select more than one at a time. I assume by "Canc" you mean the DEL key? Regardless, there's no way to multiple-select items.
