“Linking to a page that includes” is not the same as “including”. I don’t think that the requirement is satisfied.
I have been aware that Ollama is based on/uses llama.cpp since the first day I started using Ollama. It is not like Ollama is trying to hide the use of llama,cpp, but sure, it would be a good idea in the Ollama app to have a reference in an 'About' menu item, or some such place.
It is certainly possible for a new Ollama user to not notice the acknowledgement.
It's not a matter of "would be a good idea", it's a legal matter of you're in breach of someone else's copyright.
Good for you, but there are many people who aren't aware of this fact, precisely because Ollama is so non-transparent about it. It comes up regularly on r/LocalLLaMA etc.
