Okay, here's my question in as simple a format as I can put it...

IN BALDUR'S GATE II...

I'm trying to create a catch-all/opposite statement for the check...

IF ~InParty("Person") !Dead("Person")~

...thus, I need to check if "Person" is not in the party OR if "Person" is in party AND dead, which would lead me to believe it's something like

IF ~OR(2) !InParty("Person") [combined check of InParty("Person") AND Dead("Person")]~

Since there's no AND() blocks, I'm not entirely sure what to do...I've gone through every combination I can think of where I only use that OR statement and rearrange the other statements (since without an OR it is an implied AND), yet I can't seem to figure it out.

There isn't some hidden, magical blanket "ELSE" statement, is there?

ALSO, even if there's a simple fix to this specific case, I'd like to know how one would go about the logic of this regardless of what actual statements are involved (i.e. how one would code IF (condition) OR (condition AND condition) no matter what the conditions are).

Thanks in advance for any insight!

Just duplicate the blocks.

IF
  InParty("Person")
  Dead("Person")
THEN
  RESPONSE #100
    (actions)
END

IF
  !InParty("Person")
THEN
  RESPONSE #100
    (same actions as above)
END

That's a script example, but you could do the same with dialogue - you'd just have the same dialogue options in both blocks.

!(a && !b) = !a || b; in particular, !(InParty("Person") !Dead("Person")) = OR(2) !InParty("Person") Dead("Person")

The scripting language can't express a || (b && c) natively, you need to apply Boolean logic to reduce the expression to Product of Sum form; in this case, a || (b && c) = (a || b) && (a || c). You can automate the Boolean reduction using REFACTOR_*_TRIGGER.

It doesn't matter how clever you make the script lines with the OR(x) command, you'll still end up computing the same amount of script lines, even if it seems that the OR(x) makes it less. So you are better to just do a double check and use the same launcher...
