Can the bitwarden team see my passwords?

No.

Since your data is fully encrypted and/or hashed before ever leaving your local device, noone from the bitwarden team can ever see, read, or reverse engineer to get to your real data. bitwarden servers only store encypted and hashed data. This is an important step that bitwarden takes to protect you.
