Having a new insight that leads to the combination of two distinct ideas is definitionally creative.

You can say this problem needed a low amount of total creativity, but saying it's void of all creativity seems wrong.

Creative bit is figuring out two or more bits that might work together for something new. Labour part is combining that especially if it is actually laborious.

Which get to other possibility of having list of distinct things and then iterating over all pairs or combinations. Which I probably would not qualify as "creative" work.
