Even though the files don't actually exist, the runtime linker still seems to be able to handle them. The following works as expected on macOS Tahoe 26.5.1:

#include 
int main() {
  void handle = dlopen("/usr/lib/libSystem.B.dylib", RTLD_NOW);
  void (printf_)();
  (void)(&printf) = dlsym(handle, "printf");
  printf("hello world\n");
  return 0;
}
