这几种用法都正确，意思也没有什么区别，只是使用频率不同。也许是因为for 的出现频率最高，所以给你的印象最深，形成了一种语感。我将语料库的四个例句，按不同介词用法出现频率大小依次排列如下：

1. If I leave it for tomorrow, someone else may eat it and then I won't have any.

 2.“Maybe you should leave it to tomorrow.” Freya groaned, seeing what he was trying to say.

 3. 'Why not leave it until tomorrow?' she asked, suddenly panic-stricken at the whole idea.

 4. 'I suppose we'd better leave it till tomorrow, sir.' （till 比until 更口语化）
