For the most part this just works, but functions within tagged markup get weird indent assertions, e.g.,

        ${collection.map((item) => {
          const { prop1, prop2 } = workWith(item);  // eslint: expected indentation of 4 but found 10 (indent)
          return html`  // eslint: expected indentation of 4 but found 10 (indent)
            <${Widget} prop1=${prop1} prop2=${prop2} />
          `;
        })} // eslint: expected indentation of 2 but found 8 (indent)

So I'd request an eslint plugin where you could specify the name of the template function, and make the linter comprehend it, or directions to the resources I'd need to implement one.
