fpc has chm "compiler" classes to make CHM files.
TChmProject is in chmfilewriter unit and TChmWriter is in chmwriter unit 
(both in packages\chm\src\).
And there even is a GUI app to make chm files somewhere in Lazarus or 
fpc examples :) I don't remember where exactly, because I did make my 
own chm help maker application (it took about a day using existing chm 
writing functionality) before I discovered that existing one. BTW I 
posted my chm maker (app with sources) about two years ago on this (or 
fpc) list ;)

Regarding LHelp - I myself package LHelp executable with the main app 
and help files so I know that LHelp is besides main app.
You can register your help format system-wide and install LHelp in a 
different place from your app - as with any other file viewer your app 
may need :)
