Since this is an issue related more to the municipal water supply for manual firefighting, this should be handled by the Architect.
If I were in your place I'd push this back to the Architect stating that determining fire flow is not part of sprinkler system design, the two are not related. Determining Fire Flow isn't rocket science, there are a few things you've got to know when determining the requirements, that's the only real tricky part. Craig L.

The project is in a rural setting so fire pump and tanks are being used. Is it reasonable for the AHJ to expect the NICET certified designer to perform this duty or shouldn't this responsibility fall back onto the Architect who in this case would be the EOR? Regards, G.

Fire flow requirements should be identified by the EOR with direction from the local or otherwise applicable fire authority. I typically make a call to the local fire authority to find out what method is used to determine fire flow. There are several different methods out there with requirements that vary greatly so guessing isn't a wise move. Once we know their approved method, we apply that info and determine what is required to meet Code. Sometimes that entails a tank and pump, sometimes not. Fire Flow is one thing that gets overlooked a lot in engineering design. We recently had one contractor telling an owner that the requirements for fire flow were ridiculous and he's never had to do that anywhere else. I hope he doesn't do much design beyond 7-11 stores with his level of knowledge of the Codes. Craig L.

Subsection 507.3 says "fire flow requirements for building or portions of building and facilities shall be determined by an approved method". In Ohio, this has been adopted direct into the Ohio Administrative Code. I'm guessing any other jurisdiction using ICC are (or will) be doing the same. Typically the local Fire Marshal will help facilitate the evaluation (to be conducted by a private fire protection/water utility contractor) and will be the one to review/approve it.

Who is responsible for this evaluation in your area? Regards, G. Tim Stone G.
