I recently purchased an older home in New Jersey and am trying to pass a certificate of occupancy inspection. Part of the requirements is to update all outlets in bathrooms/kitchen/basement to GFCI. However, there is no ground wire in any of the panels so my GFCI electric test still reads "open ground" and the outlet doesn't trip when I hit the "test" button. However, the "test" and "reset" buttons on the GFCI receptacle themselves are working properly and I put the blue sticker on the face plates that says that the system is ungrounded.

Does anyone know if this is up to code or if I will have to pay an electrician to run ground wiring throughout my system for me to all of these outlets?

You don't need an electrician if you have basic electrical skills. Code allows for old , non-grounded to be substituted with GFCI outlets provided you put a tiny little sticker on them and all downstream outlets saying "GFCI protected, no equipment ground".

Remember that a GFCI outlet's function is to measure supplied amperage to return amperage, regardless if it's grounded or not. If the difference between supply and return by more than a few milliamps (hardly anything) the outlet will trip, ground or no ground.

That's acceptable. If you can't actually install a ground, a GFCI is the recommended safety precaution, providing much of the same protection (and arguably a bit better).

Those 3-light testers are not able to test GFCIs if there's not a valid ground. This is normal.
