Only half of the job was done and that was done poorly.
Short on time so I just made notes as I read. You answered some but I will post what I noted.....
Installed 6 months ago would put in a cold season and foam should not have been installed at low temperatures.
Foam can have its own smell from off gassing.
Did you cover the foam with a thermal barrier, drywall or special paint? Check your local codes for crawlspace requirements.
Not sure what climate you are in, but ½" is neither a vapor barrier or sufficient insulation.
Once enclosed and sealed from the outside, that space needs to be included into the conditioned house volume with heating, cooling, and air circulation. Good air circulation might accomplish all three but, sending heat down there without good insulation on the walls is a problem, condensation and heat loss.
Did you or he seal the house to foundation plus the rim joist cavities?
You have sealed off that space and should have conditioned it and included it with the house air. If the odor is from the foam that may not work which makes the entire effort a failure.
