quite strongly disagree with this. You can solve the problems with fewer than 100 lines of code, but you can certainly also take it as an opportunity to flesh your programs out in OOP style. In general, programming is about what you want to do and learn, and the problems aren't designed for any specific paradigm. A lot of people have taken Advent of Code as an opportunity to not lean on any external libraries for example.

There's numerous problems from board or combat game simulations, to mazes and the intcode computers that lend themselves to be approached in OOP style. The context OP is coming from is data science scripting, it's fine to start with small examples.
