The logo as on page http://www.alarabiya.net looks like a rather special
way of writing the name, but that’s what logos are.

Do some fonts have it, and does the ligature appear in text rendering,
as opposite to display of logos? I would expect it to be a special
rendering style, much like in handwriting we produce combinations of
letters that correspond to ligatures.

Those would be the character-level tools. But normally I would expect
people to use higher-level protocols, such as commands in a typesetting
program or style sheets applied to entire blocks of text.

It’s not a logo as such, but any use that is restricted to logos should
probably be considered as external to Unicode. If there are fonts that
contain an alif-lam ligature, then I would expect it to be regarded as a
possible rendering of a character pair. Typographic ligatures are
normally encoded as characters in Unicode only if they exist as
characters in some other character code in use.
