happy to accept a PR if you want to add a new option "decoratedFunctions" to the allow option.

I'd love to. Do you have any advice for getting started?

The rule source is here.

https://github.com/typescript-eslint/typescript-eslint/blob/master/packages/eslint-plugin/src/rules/no-empty-function.ts

It is built on top of the base eslint rule which you can find in their repo.

You can use https://astexplorer.net to inspect the ast and figure out how to build the rule.
