How does a tiger lotus plant "reproduce"? I don't know the correct
terminology, so pardon my language... Does it split at the rhizome? If
so, how do I know when or where it's ready to split? If not a rhizome,
then what does it do?

It produces short runners, with new plants at the ends of them. Sometimes it
produces a new rhizome/tuber, but it's not necessary. You can transplant the
new baby plant even if it doesn't have a tuber.

As for how to tell when it's split...it's not easy, because it all happens
underground. Sometimes you can see the runner, and a new plant that is visibly
separate from the mother. But often, it just looks like one big plant, until
you dig it up and find that it's six or eight smaller ones, really close
together.

They also produce flowers and seeds, but that's not the way they are commonly
propagated in an aquarium. My Nymphaea has a flower stalk with a bud on it
again, but I don't expect it to actually bloom.
