Azoles (and other antifungals) are indeed still used in the US and there is documented azole resistance in important opportunistic fungal pathogens such as Aspergillus in the US:

Appl Environ Microbiol. 2024 Apr 17;90(4):e0178223. doi: 10.1128/aem.01782-23. Epub 2024 Apr 1. PMID: 38557086; PMCID: PMC11022549. -- https://pmc.ncbi.nlm.nih.gov/articles/PMC11022549/
Table 1 in this paper gives estimated azole use in various countries. US is lower than many European nations but still nowhere near zero.
