Measure the inductance of the MOT with the shunts in.  Remove the shunts.
Measure the inductance of the MOT with the shunts removed.  Subtract the two
values for find the equivalent value for the effect of the shunts.

Ohm's law does not apply to an AC device such as a transformer.  It's called
reactance which is a combination of the DC resistance (Ohm's law) plus the
AC inductive reactance.  It is designated by the letter Z to keep it
separated.  In some transformer designs the AC capacitive reactance also
enters into the picture but this value is usually low and ignored in most
calculations.
