WebLSA (Latent Semantic Analysis) also known as LSI (Latent Semantic Index) LSA uses bag of word (BoW) model, which results in a term-document matrix (occurrence of terms in a document). Rows represent terms and columns represent documents. LSA learns latent topics by performing a matrix decomposition on the document-term matrix using Singular ...

tap fightsWebLDA 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.
