The thing is though, one of the main points of zeppelins was to drop things. If you can't control where it goes then people can easily dodge it's flight path or it can simply be unable to go where you might want it o go in order to deliver its payload.
The L.52 zeppelin got up to around 66mph, to put that into prospective the Vickers FB 5 (the first fighter airplane) had a top speed of 70mph and the Albatros J.1 ( which was made in 1917, same year as the L.52 and focused on ground assault) had a top speed of 71mph.
It wasn't like Zeppelins were the only slow'ish flying things and all airplanes were super fast, I mean there were plenty of planes that were indeed faster, but speed wasn't the end all be all for aircraft.
On top of that Zeppelins weren't that easy to bring down, It's not like most people think, a giant balloon that you can just "pop" and down it goes. Zeppelins weren't made like that and you could easily fire through it without even hitting anything but the frame and even if you did hit a gas area it didn't "pop" like a balloon because the pressure was equal and had many other bags to hold it up.
Zeppelins were not easily taken down by airplanes, not to mention they tended to have their own defensive weapons mounted to fight off airplanes. You could do multiple strafing runs against it and it can still fly even after being hit many times. That is why they had to make things like incendiary rounds to use against them or the ranken darts that I mentioned earlier.
