Depends on what your end goal is. JAMF can make local accounts, and push them as a policy as well as resetting the passwords for those local account. However doing things this way will get out of hand quick as its really only designed to be done for "IT" accounts and not user accounts. That is unless you don't mind creating a policy for every single user you have and setting the scope up to where it targets the correct devices and removing those accounts when a user off-boards.
I think you are looking at the chicken or the egg here. Do you want identity management before device management, really you need both. If you don't have a centralized IDP like AAD, Okta, etc. you will either be allowing users to make their own accounts or manually making the accounts for the users. JAMF Pro is not an identity management tool. If and when you get an IDP look in to JAMF Connect, which does not require JAMF Pro.
