I think the Leafs weaknesses are a lack of secondary scoring, a defenseman that could be utilized as a legit shooting threat on the power play and size and toughness in the forward ranks that would make them more difficult to play against and a team that can physically wear down their opponents.
Laughton isn't even a centre, so I can't even understand why the would even bother. He also's not a legit scoring threat that's going to move the needle and he doesn't bring size or strength.
Gourde is under-sized, weak and his days as depth scorer have passed particularly when you factor in that in moving to the Leafs, he'd be dropping down to a bottom six situation with very little support scorers around him. I don't see the point in bothering with Gourde at this point.
I like what Brayden Schenn brings to the Maple Leafs. I think he could add that depth scoring, I think he would be a huge boost to the leadership group in Toronto, he would definitely upgrade the physicality of the forward group and I like his two-way game. He is clearly the best of these three options (in fact, he's the only choice, in my opinion as the other two don't move the needle at all) but I'm not really excited about the idea of Schenn until 2028. I've only seen him play a handful of games this year - so this is certainly not a qualified take - but I find his speed is definitely a notch down from where it was a few years ago and that definitely was a big part of what made him special both offensively and defensively so I'd be wary of acquiring him for his age 34, 35 and 36 seasons.
