eg：疑问词+to do=疑问词＋sb can do
I don't know what to do.
=I don't know what we can do.

那么疑问词+to do就是一个陈述语序，能否独立成句？

一般不可以
另外你所举的两个句子不等
I don't know what to do.
=I don't know what we can do.
应该是I don't know what to do.
=I don't know what I can do.
疑问词+to do句式相当于主语相同 所以省略

虽然语法上讲不通,但是老外在日常用语中经常这样讲的.

语法上不对

比较口语化
