Generation of a new FileVault key requires an account with FileVault authorization. If you already have such an account, you can use fdesetup changerecovery -personal to generate the key with that account's credentials, rather than prompting the logged in user. Refer to the section called Managing Individual And Institutional Recovery Keys on Rich Trouton's post Managing macOS Mojave’s FileVault 2 with fdesetup for details.

(Careful: if you choose to automate this process using a shared "local admin" password via Jamf, your password may need to be stored somewhere that would put it at risk of being seen by other Jamf admins, like in the script parameters.)
