You can use a simple expression for this - make all of your lights take their values from a single "master" light and control that light with a slider.

It isn't as bad as you make it sound.
You can use the spreadsheet to set envelopes for each light as a batch. Then in the Graph Editor, pull all the lights into the bin and filter on *.Intens* to access only these values. Then assign an expression or a slider value to the intensity in a group.
I've just tried it and it was quite quick.

Though it did highlight a gap in the spreadsheet, you can't set up envelopes for light flare intensity, you have to manually assign an envelope to each light, which is a bit time consuming.

Hey that Filter syntax works, I never would have figured that out.

You need the '*' at the beginning, then it searches for anything you put next.

I typed '*X' and it removed all but the X channels.

I believe you can also use expressions to control them with a Null and then animate the Null.
