I was looking at this further, and found out that
/usr/share/applications/defaults.list was officially deprecated in
4/14. See, for instance,
https://mail.gnome.org/archives/distributor-list/2015-January/msg00000.html
and also the current spec at
http://standards.freedesktop.org/mime-apps-spec/mime-apps-spec-latest.html
which instead specifies the use of a mimeapps.list at one location or
another.
Lubuntu 14.04 seems to implement some sort of mixture of the deprecated
and current spec. I have not been able to pin it down with precision.
The LibreOffice installation wrote a full complement of mime type
associations to /usr/share/applications/defaults.list. But PCmanFM does
not look at that -- it opens an ODT file with AbiWord. I have yet to
figure out what it looks at by default. Anyone know?
If I R-click on a file: Open With and check the box to make the current
app the default for opening the file, then PCmanFM writes to
~/.local/share/applications/mimeapps.list with the minimal entries
required to set the desired mime type association. And then for the
current user, ODT files open with LibreOffice.
Oddly enough, though PCmanFM writes to a mimeapps.list (named per the
new spec), ~/.local/share/applications is not one of the lookup
locations in the new spec.
I copied ~/.local/share/applications/mimeapps.list to /etc/xdg/lubuntu/,
which is a lookup location in the new spec. Then I created a new user
and found that my global mimeapps.list was ineffective.

You could of course use:

This hold a bunch of the values you'd normally set using xdg-mime
It usually contains stuff like:
application/rtf=libreoffice-writer.desktop
application/tab-separated-values=libreoffice-calc.desktop
application/vnd.lotus-1-2-3=libreoffice-calc.desktop
application/vnd.ms-excel=libreoffice-calc.desktop
application/vnd.ms-word=libreoffice-writer.desktop
Which you can change to whatever you like.
This should effect using things like:
xdg-open mydoc.rtf
from the terminal, and probably from any application that looks at xdg
mime types.
The first line in my above excerpt defines that
libreoffice-writer.desktop will handle this.

OK, a happy discovery. LxSession Default Apps does not do the same
thing as R-Click: Open With: <app> + checking "Always use ..."
If I do the latter with an .odt file, then LxSession Default Apps
still has Documents: AbiWord, but odt docs open with LibreOffice.
And abw docs open with AbiWord.
I see now also that the properties of an odt file show File Type:
OpenDocument Text. The format has its own mime type which can be
used (but is not used by default) as the basis for the kind of
granular control I wanted.
So lxsession-default-apps and pcmanfm are apparently doing something
different in the back end with mime types. I read somewhere that
there are perhaps 4 different mime type configuration files which are
respected in some hierarchy.

OR
*Right click* on the file you want to set. Let say, a Document.odt.
On the menu, choose *Properties*. At the Properties windows, select
the software you want to open as default on the "*Open With*"
combobox (drop down menu)... Then hit *OK*.
Double click the file to see if works...

I don't understand mime types very well, but it seems like the
net effect as implemented is that they don't result in very
granular control.
To be specific, I find that if I use LibreOffice Writer to
create an .odt file, a double-click on the file in pcmanfm
results in AbiWord opening the file.
I would like LibreOffice to open odt files, AbiWord to open abw
files, and leafpad to open plain text files. But
lxsession-default-apps merely sets a "Document" launcher.
Can set up finer control to open some files according to their
extension?
