She signed the statement. And the note she wrote to police the next day made it clear that (as davefoc pointed out) she quite understandably regretted implicating Lumumba.
For the millionth time, I'm not saying that means she was guilty. I think Knox was innocent of Kercher's murder. I'm just opposed to the way people infantilize Knox, as if there could have been no other conceivable outcome for that interrogation than her signing a statement accusing an innocent man of Kercher's murder. Obviously she could have accused Guede, which would have been much more in keeping with the prosecution's theory that Knox and Sollecito were only trying to cover up their involvement. But just when you figure she would have ratted on Guede, she accused Lumumba.
In addition, she could have signed a false confession to the murder. Contrary to what some people here would have you believe, that would entail signing a statement confessing that she had murdered Kercher. That's not what she did.

So far as I can tell, the only real difference between your point of view and what some other people are arguing is over the
type of false 'confession' Knox made: everyone seems to agree it was a coerced false 'confession' (quotation marks painstakingly added!).
From what I've gathered, you believe that she was pressured into naming Lumumba - hit on the back of the head, told she'd be in jail for 30 years, etc - and caved in to make the interrogation end. If true, this would be a 'coerced-compliant' statement. Others think that - having been told there was hard evidence she was at the scene, and having been told she might not remember it because she was 'traumatized' - she momentarily came to half-believe she might have been present (I say half-believe, because her subsequent written statement made it clear that the memory of being at Raffaele's was always stronger). This would be a false internalized statement. As I understand it, many confessions are a combination of both of these, and actually I think this is probably true in Amanda's case as well.
Given that, as davefoc rightly pointed out, we have very little information about the context from which these statements emerged, it seems to me that either of these theories is valid. For me, the possibility that there was an internalized element to Amanda's statement seems very likely, since it fits with Amanda's own testimony about the interrogation and her note written in the aftermath; I also find it fairly unlikely she would've known enough about these kinds of statements to convincingly fake one. I'm sure that fear played a part in her breaking down as well. But without a tape of the interrogation, we can only theorize.
Intuitively, I certainly think it's easier for many people to understand why someone might be pressured into confessing with threats and violence than it is to understand why someone might truly come to wrongly believe (even briefly) they might have been present at a crime. But the latter is no less a true and documented occurrence than the former, even if less intuitively understandable - to refer to it as "woo" just shows an ignorance as to the accepted theories of why people falsely 'confess'. I'm also not sure why you think this would 'infantilize' Amanda, since if she was coerced into making either type of statement I would hold the flawed and coercive interrogation tactics to be responsible for it rather than Amanda herself.
The distinction between confession/accusation with elements of confession has been covered, but just to say: if someone is coerced into making a confession, then obviously they are only going to be coerced into saying something that the police
want them to say, something the police 'know to be true'. I highly doubt the police had any thoughts at this stage that Amanda was the rapist/murderer; if they suspected her of anything, it was covering up for the
real rapist/murderer. And so this is what she 'confessed' to.
