I am not aware of full build gravel bikes with rim brakes. Even All City retired the rim brake Space Horse 4 years ago. Surly has the Cross Check in flat bar as a rim brake bike still, but I would end up spending a good bit to convert that to how I want a bike to be spec'd for gravel riding.
As mentioned, Black Mountain still sells rim brake frames and you could pay to have Mike the owner build one into a full bike.
GRX with Canti makes 0 sense. A major part of GRX is hydraulic brakes. Just buy any regular mechanical rim brake Tiagra/105/Ultegra shifters with matching speed rear derailleur, a GRX crankset, and GRX front derailleur- that is now the setup you are looking for.
