For scale, the objects with orange bands are slightly larger than shipping cargo containers.

Does a tether space elevator make any sense for gas giant atmospheric harvesting?

Yes, there are a number of studies on the subject. It's probably going to require a fairly advanced civilization for support, although. It might combine nicely with ISRU for fuel to maintain tether altitude. Tethers can also extract power from a magnetic field, and could serve as a power source as well. Just Google scholar Jupiter and tethers.
The image shows a rotating tether and Jupiter. In the foreground a visiting ship is coming in to collect the He3.

A rotating tether can significantly reduce the required orbital velocity from the rocket side. Enough to make the requirements to reach Low Uranus Orbit to be the same as Low Earth Orbit (if you include the faster rotation speed of Uranus compared to Earth).
(also helps reduce reentry velocities, which makes a chemical, reusable Uranus launch vehicle feasible.)
Current materials could suffice for the ~5.5km/s tip speed you'd need. The mass ratio wouldn't be great, but it'd be doable.
