You might consider using a programmable relay for this too. They are just a very small PLC and they are getting quite affordable. To see one line check out Allen Bradley / Rockwell's Pico controller. I'm sure there are others at better prices, I just know this one is easy to find and you can download the software for programming Pico's free.

That's what I am afraid of ;-) I am a computer junkie as it is. I have 9 PCs running around here doing different things. (30 years at IBM may have something to do with that) It was my wife who demanded that I try to keep this simple. I am still chewing through the PIC links and thinking of things I could do.
So you either did not read the original, or you have no reading comprehension. I'll eliminate the need for you to read the original, by recapping: The LED's are optoisolators. The output side will control low voltage to his existing setup, which is not in question. He's looking to build a controller. His question is not "how do I connect the LEDs to the controller?" He's asking whether he ought to build the controller with 4xxx CMOS or with a small processor.
In fact, he does, probably far better than you. But that is irrelevant. It is an existing system. He's not connecting the system to the mains - it is already connected and inspected and he's been running it manually for ~ a year, AIRC. Nothing in what he plans to do is associated with isolating from the mains. He's working on the low voltage controls.

Bullshit. There is no kludge. Can't you read?
