1Password has a handy solution to that problem: https://support.1password.com/generate-security-questions/

They have a bunch of "standard" questions in the drop-down list, like "first grade teacher" or whatever, but you can always just type your own since they're merely designed to be helpful. The answers they generate are built on top of their normal password generator, but I found the "battery horse staple" variety makes for the least amount of headache, although you could probably generate a PIN format if the target website accepted it since it'd be much easier to read to a customer service rep if it came to that (err, aside from the social hurdle of "what is your first grade teacher? ... 8675 ... no, I mean the teacher? ... yes, my answer is 8675" nonsense
