Lockheed has Orion, they could modify it for Vulcan or Falcon. Overkill for LEO but at least it's functional. Realistically NASA will have to go through another round of requests for proposal, though I don't know how much interest there will be after Boeing's troubles and with ISS disposal looming.

I've seen papers outlining an Orion docking to the ISS. It was considered as part of the conops back when Orion was part of Constellation rather than Artemis.
