Teams require leaders, and people who create ideas, who develop ideas, and people whose role it is to comment and help improve plans. 第一个and 是否多余？或是否存在其他问题？

不是多余的。 第一个and 是用来连接teams... 和 people...这两个大概念上的分句， 第二个and 是用来连接关于people的三个分句。例：The parents , and their three children, Tom, Betty, and Peter, are all good at music. 这句话中的两个and 类似于你的句子, 都不能缺了。
