I still am no merkle tree-super expert and have problems to judge this issue, any further comments on this are appreciated.

Yes MerkleProof for non-existent values are tricky, but possible. In the end it comes down to following the path of the nibbles and we can be sure the value does not exist, if:
- if we find a branch and the slot for the next nibble is empty
- if we have a extension or leaf and the path does not match the target
Here is an example where I implemented this:

A bit the same question as on the block library, are you open to do a PR here? Does this conform with the license requirements of slockit code base?
