I am not quite sure what 'out group' means, but I think it is the equivalent of 'scapegoat'.

So, first of all, Fascism and Mussolini did not have the same apparent ideological graniticity as Nazism and Hitler, for whom hatred for Jews and their alleged being behind all of Germany's enemies has been evident since before he came to power. I say apparent because in any case the Germans were happy to make exceptions to their racial hierarchy in order to include the allied country of the moment. Even the Japanese were called 'honorary Aryans'.

Italy's main enemy in fascist rhetoric was the 'perfidious Albion', i.e. the United Kingdom, as the main power in the Mediterranean that Italian nationalism claimed for itself. The text of Mussolini's war speech delivered in 1940 is a good summary of what the main points of the propaganda were:

"Let us take the field against the plutocratic and reactionary democracies of the West, which, at all times, have obstructed the march, and often undermined the very existence of the Italian people. Several lustrums of the most recent history can be summed up in these phrases: promises, threats, blackmail and, in the end, as the crowning glory of the edifice, the ignoble corporate siege of fifty-two states (the sanctions against Italy after the aggression against Ethiopia)"

"We take up arms in order to solve, after the solved problem of our continental frontiers (the reference here is to the Alpine frontier conquered in the Great War), the problem of our maritime frontiers; we want to break the chains of territorial and military order that suffocate us in our sea, because a people of forty-five million souls is not truly free if it does not have free access to the ocean".

"This gigantic struggle is but a phase in the logical development of our revolution; it is the struggle of the peoples poor and numerous in arms against the starving people who fiercely hold the monopoly of all the riches and all the gold of the earth; it is the struggle of the fertile and youthful peoples against the sterile and waning peoples; it is the struggle between two centuries and two ideas"

I hope the translator was not misled by a somewhat outdated Italian :)

Nor should it be forgotten that as fascism approached the war it increasingly embraced German anti-Semitism, complete with racial laws in 1938 that divided the 'Italian race' from the 'infiltrated Jewish race' (no offence to anyone, these were the words of the time). Nazi rhetoric also became Italian rhetoric as the war and military defeats continued. By the time of the Italian Social Republic, the collaborationist government of German-occupied Italy, Fascist rhetoric is now indistinguishable from Nazi rhetoric and speaks openly of a Jewish conspiracy.
