ISIS is running on data-link layer, so ISIS neighbor establish should have nothing to do with IP. Why they can’t
establish neighbor relationships when local interface IP address and remote interface IP address are not in the same
IP segment?

ISIS neighbor establishment has nothing to do with IP address. But ARP can ensure the reachability of neighbors, if the address is not unnumbered, the local interface can check remote router’s route, if the route of remote router and local router’s route is not belonging to the same IP segment, the two sides can’t establish neighbor relationships.
