You’ll need to use motion controls to catch Pokémon in Pokémon: Let’s Go Pikachu and Let’s Go Eevee, regardless of whether or not your Nintendo Switch is docked, and they’re compulsory throughout the games. The official confirmation and clarification of how exactly the new catching system works is as follows:
“In handheld mode with both Joy-Con attached – you are still required to move around to aim, but you press a button to throw the Pokéball. It is not touch screen like on a smartphone because the Switch is quite a bit heavier than your smart phone.”
In other words, if you’re playing Let’s Go out and about – or just handheld at home – you’ll still need to wave your Switch about to aim and catch Pokémon. It’s just the press of a button that actually launches the ball, presumably once you’ve lined it up.
