What's the relationship between the tiller and the rudder when it comes to
steering? I understand that most large aircraft have a separate tiller
wheel
that can be used to turn the nose gear on the ground, but it also seems
that
the rudder turns the gear, too (?), at least during landing and take-off.

Typically the rudder pedals provide about 8 degrees of nosewheel turning in
either direction. The tiller is used when when sharper turning is needed.
