How to include data-json in Drupal 7 Webform form?

Question

Drupal

I transplant the form with json and js into Drupal 7. Almost everything works out except for editing the tag itself <form>. The fact is that the creator of the form included the data-json field in it, which pulls up certain data for calculation. In addition, there is an id that is tied to the JS library. How, without resorting to hooks (because there are several forms and different content), to dynamically attach JS and JSON to the Webform form? The customer is already trampling with his feet - he wants the result, and I'm in a stupor.

In general, the question is not entirely clear, but what prevents you from adding logic for all forms in one hook_form_alter() hook?
Working with Drupal 7 and not using hooks is a very strange decision.
