Can I route those LFOs outside via the MOD output?

Of course, you can route all automators to the outputs as well of course. In your case just use the MOD as destination in the modulation matrix (function 01 in the tracks 1..6)...and even better you can route multiple LFO to one output for example and much more....

What will happened to the existing MOD values on this track

They work together. Play a melody on eg the CV output, put the LFO with a small range on it and you get a vibrated melody...and so on

I see, they just add up. Is there a way to make MOD values affect one of the parameters of the LFO instead of combining them?
Also, would it be feasible to activate automation only on certain steps of the sequence or only on certain patterns?

All destinations are added up and depending on the destination, added up or overrule the current value.
There is no need to use the MOD values to change the LFO (or other automators). You can change all values from all automator slots in every FX column including starting and stopping which answers your 2nd question also already.
