However, how can I extract all of the files included above to {tmp} without manually specifiying everything (since I'm trying to desing the code so that anything in the Include folder will be extracted to {tmp})?

For not so old versions of Inno Setup you can use:

[Files]
Source: Include\*; DestDir: {tmp}; Flags: dontcopy

[ code]
function InitializeSetup(): Boolean;
begin
  ExtractTemporaryFiles('{tmp}\*.*');
  Result := True;
end;

If you use @files: in the path of any of the DLL functions they will be extracted automatically before the InitializeSetup function.
So I recommend you change to {tmp} in the DLL functions, or specify a destination other than {tmp} for them using the dontcopy flag.

function ISArcExtract(CurComponent: Cardinal; PctOfTotal:double; InName, OutPath, ExtractedPath: AnsiString; DeleteInFile: Boolean; Password, CfgFile, WorkPath: AnsiString; ExtractPCF: boolean ):boolean; external 'ISArcExtract@files:ISDone.dll stdcall delayload';

change to:

function ISArcExtract(CurComponent: Cardinal; PctOfTotal:double; InName, OutPath, ExtractedPath: AnsiString; DeleteInFile: Boolean; Password, CfgFile, WorkPath: AnsiString; ExtractPCF: boolean ):boolean; external 'ISArcExtract@{tmp}\ISDone.dll stdcall delayload';
