Not a single tool. Although some conversions are possible using
different tools. Applications are listed as available under /usr/ports
unless stated otherwise. Ports that are marked with * are those that
I've used with reasonable results myself.

RTF -> HTML: textproc/rtf2html or textproc/unrtf
TXT -> HTML: I've used a simple perl script to do this in the past, but
             I guess the textproc/txt2html does something similar.
TXT -> PDF: print/nenscript or print/enscript-letter to make postscript
            files from text, then ps2pdf from print/ghostscript8 to
            create PDF from the postscript files. *
PDF -> HTML: pdftohtml from graphics/poppler-utils *
HTML ->PDF: Firefox supports printing to a PDF file.

It seems LIT files are based on MS' CHM format. Maybe textproc/chm2pdf
will convert them to pdf?

There is an open-source tool for e-books (LIT format, among others):
http://calibre.kovidgoyal.net/ It is not available via ports though.

DOC  -> TXT: textproc/antiword *
HTML -> TXT: textproc/html2text
PDF  -> TXT: pdftotext from graphics/poppler-utils *

P.S. A lot of public domain e-books are available in different formats
