Yeah, I can see where you're coming from. I'm not familiar with SO, so I can't speak to it directly, but I do think that if a dungeon was created by or taken over by large sized creatures, they would build it to an appropriate scale or widen the passages (if possible). On the other hand, if they're simply exploring the area, then they have to deal with it (which will likely knock the encounter difficulty down a peg).
You could give them a potion of reduction for situations like these (if you use the house rule that potions are a bonus action, it doesn't even cost them much in terms of action economy). Overall though, two slaad against 5 PCs with 75ish HP seems like it's meant to be an easy fight anyway, so I wouldn't sweat it.
I do agree that it's annoying when the dungeon isn't appropriately sized for it's inhabitants.
