A problem could be distros heavily sponsored by a single US company, like Red Hat. But it would still be possible to set up a clone or switch to another somewhat similar Linux distro. Compare this to switching away from Apple or Microsoft - there is no other source for MacOS or Windows.

Ubuntu, Britain
SUSE, Luxembourg/Germany

But HQ country is not so simple or relevant for Linux distros. Debian, for instance is in principle run by a New York nonprofit (SPI). In practice, contributors are worldwide, and source code is freely available.

If Trump took over SPI (with domain name and cryptographic keys), developers elsewhere would quickly reform as, say, "Doubian" and Debian users could switch with a simple reconfiguration.
