I have an Android. I want to let my kid use the phone, but without a separate account. I basically want to say "Enable Kid Mode", and I specify what apps he sees. To get out of Kid mode I need a PIN.

This is basic level protection.

How do I do this?

The separate account is, in fact, the way to do exactly this. Settings->System->Multiple Users->Add User. Follow the on screen prompts to set it up the second user with Parental Controls. Selecting which user to access the phone as is available on the lock screen.

Thanks - will try it.
