There's I Should Write a Book About This. Also It's for a Book when the book is just an excuse for the interview and the questions are for something other than a book.

I Should Write a Book About This: I thought this trope only relates to characters that are involved in the story's event? Alice, as noted above, is not in any way involved in whatever happened to Bob; she just heard him recalling it. Does it count?
It's for a Book does not apply; Alice is indeed in a Writer's Block.

I think I Should Write a Book About This applies to the situation as much as who the actual author is — often the person whose experience it is isn't a writer, so they collaborate with someone who is — but there's also just Based on a True Story for when the writer is telling someone else's true story. I think the two can overlap depending on how they arrive at the decision to tell the story.
Is there a trope for a writer character tells one of their acquaintances that something happened to them is worthy of a book, news report, etc?
My particular case looks like this:
Alice is a writer. When she meets her old friend Bob, Bob tells her what's going on about his romantic life (readers already know exactly what happened in his story). When he finishes, Alice tells him, "Don't you know what you said just sounds like it comes straight out of a novel? Would you mind if I can interview you later as an inspiration of my new book?" Bob refused her invitation politely.
To the reader, the werk is clearly not written by Alice.
