On the basis of the information available, no I don't think she was leading him on.
I think she was scared what might happen because he was a very senior person in her industry. So she is trying to put him off as politely as she can without making him angry.
It's easy to say 'Oh she should just have told him to get lost' but what might have happened if she had? He might have got her sacked, or made her life difficult in low level ways. That sort of thing can be very difficult to prove, so it's not like she could be sure that she could just run to HR and complain if that was the outcome. Even if HR are supportive, who wants the hassle and stress of that?
It was a very difficult situation for her to be in and I feel sorry for her that she had to go through it.
