Hello @jerry.houser
I hope you are doing great. My name is Hilda and I'll be assisting you with your request.
If you would like to disable autofill for all your site, you can do it from the LastPass extension, by disabling the option call "Automatically fill login information" under general settings, here is a related article that can help Manage your LastPass browser extension preferences
However, if you would like to make it happen only on one site or a few in specific, you must do it from the item itself, by unchecking "autofill", for more information of how to do it: Disable autofill for sites

Hilda
