Can LAAFU effects be modeled?

One of the problems with the Voynich MS text is its relative lack of repeating sequences of words. This is aggravated in case one assumes that the text is a verbose cipher.

I think a verbose cipher that uses some source of entropy (dice, cards) to add random nulls (Mark Knowles style) or pick one of the few ciphertext variants (the Naibbe) won't necessarily produce extra repeating sequences and, on the contrary, can effectively hide existing ones. Only one-to-one context-free verbose ciphers would need to explain the lack of repeating sequences.
