If we know our place in society and accept that we are all equal but some are more equal than others...
The OP seems to be under the assumption that Animal Farm (published in 1945) is less about the rise of the Stalinist bureaucracy in the former Soviet Union then it is about communism as an ideology (a common assumption about George Orwell's book is that it is an indictment aimed towards discrediting communism, something that upon a closer reading of both the book and of the author's own life is proven to be factually untrue IMHO).
Lenin never sought outright to create a single-party dictatorship; His writings prior to the October Revolution of 1917 focus on the creation of a commune-state, i.e. a state based on the Paris Commune but suited to the backwards conditions prevailing in Russia at the time.
Furthermore, this commune-state was to be based on the Russian soviets that had reentered the Russian political scene after the monarchy was overthrown in the February Revolution of 1917. They had been suppressed by the monarchical regime since the failed 1905 Russian revolution.
These soviets of workers, soldiers, and sailors (and later peasants) were to be the basis for a new type of state not beholden to one sole party.
In fact, during the Second All-Russian Congress of Soviets the Bolsheviks willingly chose to be in favor of a multiparty government that was to be responsible to the soviets (and to the C.E.C., which functioned as the legislative branch of the new soviet government while the Sovnarkom functioned as it's executive branch).
Even more so, eyewitness accounts by journalists such as John Reed noted that at the Peasants' Congress that Lenin (who attended the Peasants' Congress) appeared to be all in favor of a future Constituent Assembly.
From John Reed's
Ten Days That Shook The World, Chapter 12, The Peasants' CongressLink:

Lenin:
“However,” he went on, in an unmoved voice, “nobody will deny that the present Government of Russia has been formed by the Bolshevik party...”
Lenin continues:
The present Government is a Government of Soviets; we have not only invited the Peasants’ Soviets to join that Government, but we have also invited representatives of the Left Socialist Revolutionaries to enter the Council of People’s Commissars….
And finally he says:
“The Soviets are the most perfect representatives of the people—of the workers in the factories and mines, of the workers in the fields. Anybody who attempts to destroy the Soviets is guilty of an anti-democratic and counter-revolutionary act. And I serve notice here on you, comrades Right Socialist Revolutionaries—and on you, Messrs. Cadets—that if the Constituent Assembly attempts to destroy the Soviets, we shall not permit the Constituent Assembly to do this thing!”
In other words, a stern warning was given out by Lenin and the Bolsheviks that the Constituent Assembly would be shut down IF it moved to obstruct or dismantle the soviets, prior to it's first (and last) meeting months later.
And, according to the very long and analytical book by Alexander Rabinowitch
The Bolsheviks In Power, that is exactly what it tried to do and for that reason was shut down by the Left SR-Bolshevik government shortly after it's first meeting.
IMHO, this leads me to believe that the Constituent Assembly was the very embodiment of the counterrevolution Lenin and others feared. It was a legalized (and legitimated) way of ridding the country of the soviets.
And this all came prior to the single-party state's sudden formation, so allegations of the nature that the Bolsheviks only wanted their own dictatorship to trample over the "democracy" of the Constituent Assembly increasingly appears to be false as more and more evidence is examined by historians past, present, and future.
