Its been recommended (at least as long as I've been using Lastpass, so a few years) that you keep autofill disabled, for exactly the reason mentioned in the article. "Also, this would not work if multi factor authentication was on, so you should probably enable that as well." If you have something as important as a password manager (ie something that holds the keys to ... everything), then MFA is a must. If you use LastPass without MFA, then you're probably asking for trouble.
