We do not. We can’t even move solar energy from earth orbit down to earth at any scale that would be economically viable or really even useful.
We lack the material science to build something that large but still light enough to be physically stable AND somehow collect and transmit energy.
We also lack the technology to stop it from being destroyed by space debris even if we could somehow build it.

There isn’t a requirement for a Dyson shell to transmit energy. You could just envelope the sun in habitats that use the energy they collect locally and that would meet the criteria of a Dyson shell (and a K2 civilization).

Sure but that’s even harder!

It requires more material and financial resources, but isn’t necessarily harder. Transmitting energy effectively to reduce heat, or managing the excess heat starts running into some pretty tough limits of physics. Most of the issues with spinning habitats are engineering problems within the capabilities of our current technology level and materials science. It’s just super expensive and has terrible ROI for now.
