You can't check the current or voltage between any node and ground directly, those are not real world wires they're virtual connections and are insubstantial, there's nothing traveling through them to measure. If you want to measure the total current of that circuit measure the current going through the voltage source.
This is a very basic circuit so measuring the current from the voltage source will be the same as putting a current probe at your boxed location.
If you every create circuits more complicated than this and need to measure current at a specific location you'd have to insert a resistor into the schematic as a reference point, simple chose a low value for resistance.
There is a way to add parasitic values to the trace lines in LTSpice, but even adding these parasitic values will not allow you to direclty measure anything associated with a wire, you can only ever measure from node points.
