If I understand correctly, the main problem here is that if a password manager at some point asks you for a password in an online environment, they're subject to coercion. This is especially dangerous if you're using auto-updating code like Javascript in a browser or code on a remote service, because it could get backdoored at any time and you wouldn't notice. Isn't the real problem auto-updating code with access to a network? 1password.com is certainly another vector that fits this description, but if you don't trust AgileBits to manage 1password.com securely, why would you trust them to manage the app on your machine securely? Or the auto-updating Chrome plugin? I'm not denying that there's more surface area by creating a login, but I think it's a false dichotomy to say that the app is "offline" and the website is "online". They both have network access, and if AgileBits or a random hacker can change the app's code, they'll do that. That change will be mindlessly delivered to your computer, and the bad guys will have all your passwords.
