Isn't it possible for a neighbor to throw something in the toilet that
eventually clogs the city sewer line? If this happens, then subsequent
flushing or use of water would cause a backup. Or is the city sewer line so
large that nothing passing through a toilet could possible get stuck there?

city sewer lines are typically very large, to handle water
infiltration during storms.

tree roots can attack sewers, and cause much grief
