They have about as much knowledge as a password manager can possibly get away with. Every time you login to a site, an event is generated and sent to LastPass for the sole purpose of tracking what sites you are logging into. You can disable telemetry, except disabling it doesn't do anything - it still phones home to LastPass every time you authenticate somewhere. Moreover, nearly everything in your LastPass vault is unencrypted. I think most people envision their vault as a sort of encrypted database where the entire file is protected, but no -- with LastPass, your vault is a plaintext file and only a few select fields are encrypted.
