you don't need to. but then for the sake of easier maintenance you want to containerize it (docker/podman), and be careful to not overload your pihole device, because then DNS service will go away or get large delays (especially if the device is overloaded with ram usage, and swaps a lot)

besides, my experience has been that swapping to USB storage on a raspberry pi is unstable enough to cause a kernel panic every few months
