I had a look at a GP7200 cutaway. Interestingly it seems the first 5 or 6 compressor stages turn with the fan.
That's common design practice for both Pratt and GE. GE refers to the compressor stages on the LP shaft as the "booster" or "booster stages", Pratt simply calls that the LP Compressor.
The only big turbofan engines I'm familiar with that don't have that feature are the three spool Rolls engines.
