Can knights work against extreme AI?

Noob here. Haven't played any multiplayer games. Been having fun playing AI matches so far.

I can comfortably beat 2 extreme AI with a Feudal tower rush paralyzing one of them, building a castle as soon as I can to defend myself against the other, then transitioning to mass ranged army like longbows.

However I am having trouble even beating one extreme AI with FC into knights (as Cumans). I find my early raid somewhat effective but soon AI will produce pikemen to counter. As this point I mostly give up raiding because it takes too much micro against pikes. Then I would find myself completely lost. What do I do next? Knights + crossbows cost so much gold it doesn't seem sustainable, but without ranged units my knights would charge into pikemen + monkas. Should I build trash units + monks and maybe siege units myself? Things is they are so difficult to micro well especially against AI (and remember all the while we gotta keep econ going).

I wonder what you guys do with knights against AI? Can knights play a different role in multiplayer games due to human limitations on micro ability?
