In my opinion, pre-built binaries and an easy-to-use front-end are things that should exist and are valid as a separate project unto themselves (see, e.g., HandBrake vs ffmpeg).
Using the name of the authors or the project you're building on can also read like an endorsement, which is not _necessarily_ desirable for the original authors (it can lead to ollama bugs being reported against llama.cpp instead of to the ollama devs and other forms of support request toil). Consider the third clause of BSD 3-Clause for an example used in other projects (although llama.cpp is licensed under MIT).
