Maduro’s VP has expressed a willingness to cooperate with Trump

What makes you think that? Is your news diet limited to Fox/CNN/NPR/etc?

FYI here is a translation of her speech, and here is the video of it.

Her subsequent statement (on Instagram, in English, and which some media is describing as "conciliatory" while selectively quoting from it) can be read here. When you read it in full you can see she is not recanting her earlier statement and is clearly still not distancing herself from Maduro. She is (consistently with him) imploring the US to follow international law and respect Venezuelan sovereignty.
