Is it really that hard to add a few lines to your LaTeX jobs ?
You could write a short script that does it for you.

LyX and LaTeX2HTML were developed independently,
perhaps with different aims in mind.
Since LaTeX2HTML has been around longer, your question
is best addressed to the LyX development team.

Not at all.

The  url.sty  package is a graft of the URL concept into
TeX --- which was devised long before the internet was
even conceived.

On the other hand, the URL idea was well-known when
LaTeX2HTML was developed, so is fully incorporated into
its design (and perhaps similarly for LyX).
However, since many LaTeX documents were already
in existence (and continue to be written) without reference
to hyperlinking, then it is quite understandable that
a package needs to be loaded to allow hyperlinking markup
to be properly interpreted.

For LaTeX2HTML this is html.sty  --- which does all that
is done by  url.sty  plus a lot more.
LyX chooses to just use  url.sty .
(It could choose to use either  html.sty  or  hyperref.sty
as more sophisticated alternatives; each of these loads
  url.sty  as part of the extra features that are offered.)


If you use LyX to write your LaTeX documents, there is
no a priori reason why it should know that you intend
to also process your documents with LaTeX2HTML.
That is your choice, and you should be prepared to
adjust your manuscripts appropriately, or ...

  ... ask the LyX team to implement better compatibility
for subsequent processing with LaTeX2HTML.

If you are using the LyX interface to compose your LaTeX
manuscripts, then that is a question for the LyX team to answer.
