What does かの add to ようだ?

〜ようだ is a direct comparison: "A is like B."

〜かのようだ emphasizes that it's not really true, but it looks/feels that way.

The か in かの is the same か that expresses doubt or uncertainty — like in 「何だかおかしい」(something seems off). It creates a stronger sense of "this isn't reality, but it sure looks like it."

Compare:

まるで台風が通り過ぎたようだ。

→ It's like a typhoon came through.

まるで台風が通り過ぎたかのようだ。

→ It's as if a typhoon came through. (but it didn't)

Both sentences compare the situation to a typhoon, but かのようだ pushes the gap between what's real and what it looks like.

Note: 〜ようだ can also be used to present someone as an example ("I want to be like that person"), but 〜かのようだ cannot — because かのようだ always implies "it's not actually true."
