None of us were there so we can't know what really happened and will of course give you the benefit of the doubt, but a few thoughts...

I don't know of any public (vs. private drives and parking lots) residential areas that have speed limits of 10mph. It seems cyclist fell into a lapse of innattention (not an excuse) or there was some other unexplained circumstance that lead to the incident.
Riding hard (which is irresponsible in places like this) can make one less attentive, crashing and pain can make one say stupid things (like blaming your daughter) All cyclists I know want to avoid at all costs crashing, especially when riding 25mph on pavement. This means swerving to avoid potholes, let alone a young child. No cyclist, except a deranged one with issues, wants to intentionally crash into a child.
Rage can make one react stupidly in response to a person who was not riding responsibly, but also not intentionally endangering you and your daughter. After getting kicked, they probably left the scene feeling less bad about it and learning less of a lesson vs. had you (done the near impossible) and offered to help them up while calmly lecturing them about speed and attentivess. But that is easy to say after the fact.

Drivers kill people daily due to lapses of inattention and other irresponsible behaviors.
