Is there any IFC class to classify an earthing rod?

Iā€™m not an expert on this, but think the closest generalisation of earthing rod would be the IfcCableSegment and you can apply the predefined type: CONDUCTORSEGMENT. Alternatively IfcProtectiveDevice.

IFC4.4 will likely introduce an IfcEarthingElement as a subtype of IfcFlowTerminal with several predefinedtypes including GROUNDINGROD.

For IFC 4 (awaiting IFC 4.4) I would suggest IfcCableFittingType with PredefinedType EXIT (or USERDEFINED with attribute ObjectType GROUNDINGROD)
