Recip fee only checked and charged when coming IN through Immigrations at SCL*. Anyone who enters Chile over land is not charged the fee and it is thus never checked for when going OUT of the country.
In the case of a newly acquired in-country USA passport, the tourist card and a simple explanation if asked would easily explain the lack of an entry stamp.
I find this thread interesting as Chile technically does not recognize dual citizenship though I personally know a Chilean with dual passports like the hypothetical examples above and he has never had a problem.
*I am still trying to find out if other Chile international airport entries like in Arica check for and charge the fee.
