Infor documentation doesn't always show us all the possible substituions available. Just for giggles, have you tried the usual suspects like tpid_O_COUNTRY_CODE?

Or L1_O_COUNTRY_CODE

Another thought would be to modify your process (laws_out_91_ghx or laws_out_91 or whatever you might have assigned in ED10). With Infor support you might be able to add code to the effect of
If tpid = XX then shipto_country_code = US
