Help! Renewal of passport

Question for the group,

My gf and I are confused on the process.

My Gf, Venezuelan and Italian citizen, is looking to renew her Italian passport (Venezuelan is expired, currently a perm resident from Venezuela in the US with valid green card)

We are looking to renew her Italian passport (she is an Italian citizen through descent NOT registered in AIRE) before it expires in December.

What do we need to do/steps? We are going to use an honorary consulate in charlotte and have an appointment in September but they mentioned needing to be registered in AIRE, we can’t even fill out all the proper information on AIRE paperwork because she never lived there. She was born in Venezuela and an Italian citizen after….. no naturalization certificate either as they don’t issue for this scenario.

All she has is her Italian passport that says she’s an Italian citizen.

Subsequently,

We are wanting to obtain Italian citizenship for her son via descent, what is the accurate process on this?

Thank you for your time

Descent is GM/GF (lived in Italy- moved to Venezuela) - mother born in Venezuela (passed citizenship from her to her daughter (my gf)

On fathers side grandparents also passed descent the same way.
