First, in any case you need a pallet to call a smart contract (SC). Pallet-contracts and pallet-evm provide the functionality to call a WASM SC or Solidity SC respectively.

There can be many reasons to have other pallets in your runtime interact with SCs or the other way around. This post on the Polkadot Forum can maybe help you get a grasp of it: https://forum.polkadot.network/t/urban-planning-in-the-paraverse-with-ink/2617
