So what you're saying is that Lao Shan only ever moves when a Fatalis is in town thus you can only fight it if Fatalis is in the game.

Oh hey Lagiacrus, what're you doing up in the peaks?

See, a monster can be put in the game regardless of whatever gimmick it has or relationship with another monster (Teostra without Lunastra in 4th gen though that could change with this).

What if Lao was just y'know, hungry? What if it was just strolling down its usual Migratory route to find more food without pressure from Fatalis? What if the route was where the Fort is? I mean the Guild must keep tabs on them and prepare for wandering Lao Shan. At this point the only direct threat to it are hunters. At this point it isn't driven by fear but it's driven by instinct and if its only threat was 4 potentially lethal hunters chasing it down in a corner? You damn will bet it will try to fend them off.
