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.
They'll use "advanced interrogation techniques" to beat the passwords/access to your accounts out of you if they deem you a serious enough threat.
