Lastpass uses client-side encryption. Which means your passwords are encrypted with your master password before being sent to their cloud. And when your passwords are downloaded from the cloud they're decrypted locally using your master password. Your master password isn't stored in the cloud. This is kind of the same idea with how Whatsapp/Signal etc works with end-to-end encryption; your chat messages aren't stored in plain text on their servers, and only your device can decode them.
Even if someone did have access to the Lastpass database they'd need your master password. So as long as you use a decent quality master password it would likely take too long to brute force.
So if they wanted to steal all your passwords they'd most likely have to infiltrate the Lastpass extension to make it leak your master password back.
I use Bitwarden which I think works the same way.
