WebLDA is a word generating model, which assumes a word is generated from a multinomial distribution. It doesn't make sense to say 0.5 word (tf-idf weight) is generated from some distribution. In the Gensim implementation, it's possible to replace TF with TF-IDF, while in some other implementation, only integer input is allowed.
