The NSA offered suggestions during the development of DES that secured it against cryptanalysis attacks which were not known to the public. So, the US government helped at least once. They provided feedback to NIST during the selection process for AES algorithms too.
Decades later, that cryptanalysis method was discovered by people outside the NSA, and they put the pieces together. That's how we know about their contribution now.
We have no new information about their input into the selection of Rjindael for AES, and maybe we never will. The same applies for the selection of CRYSTALS-Kyber and CRYSTALS-Dilithium for FIPS-203 and -204. In both cases, NIST solicits input, but the NSA provides minimal technical details.
However, the government is not a singular entity with a singular purpose. It's possible for Congress or other agencies to have goals that do not align with the NSA's mandate.
