Being analog, means film resolution can not be measured.

Film resolution can be measured in lines/mm just like lens resolution.  Lens resolution is analog and is measured on a regular basis.

To measure film resolution you would use a sharp lens, preferably wide angle so the greater DOF would reduce the effect of the inevitable small focusing errors, stop it down to about f8 and use the same resolution target used to measure lens resolution.  You would only need the center to be sharp.

Back when I was into photography in the 70s I recall photography magazines doing film tests every so often with grain and resolution being part of the test results.

And Fuji Velvia (ISO 50), according to their data sheet has 160 lines per mm at 1000:1 contrast ratio.  This gives a potential equivalent to about 22Mpixels.
