TL;DR: Last Pass is broken. All passwords at the time of the breach were taken. They also got internal secrets from a laptop and can now probably throw computational power at anything they want to decrypt.
Switch. Do not use. Change everything you have if you were using it. Treat everything as breached.
I use private browsing by default. I have to enter log ins every session.
You can still download Bitwarden and enable it in private browsing. Or you can just set your browser to clear on exit in normal sessions but still use the built in password manager. It's much more secure to use randomly generated passwords unique to each website than to use anything you can type, especially if you're reusing a password.

I use uniques everywhere with muscle memory.
Yes, search up "dictionary attack hacking"
