While simulating with LTSpice I discovered the simulator gives milliamps of inverting and non-inverting terminal current in op amps and also the same thing for MOSFETs, milliamps into gates. Here is a simple circuit demonstrating the current into a non-inverting terminal with an op amp. I will also put down that I measured only nanoamps of current into op amp inverting and non inverting terminals and also MOSFET gates in Multisim to verify that LTspice is incorrectly giving results, which leads me to believe LTSpice is seriously flawed and this should be reported to developers. Is this normal or is it a bug which should be reported to developers?
As mentioned in comments, opamps don't like their inputs to be as widely different potentials. That said, I believe LT Spice might be telling the truth. Take a look at the LT1002 schematic. Notice the series R and protection diodes between the two inputs. If the two inputs differ by more than 2 diode drops or about 1.2V, the current will be limited by the two 500 series resistors.
The current into the higher potential input and out of the lower potential input will then be equal to the difference between the two Vin sources, minus 1.2V, all divided by 1k ohms (sorry, no math fonts on my phone).
