If all we are changing is that Lenin is democratic, then he fits in with the rest of the RSDLP of the early 20th century. There's no
What Is To Be Done? and thus no Menshevik-Bolshevik split. The RSDLP stays as a united party, but a much less radicalized one. Lenin becomes a charismatic leader, probably taking over Julius Martov's position after the Russian Revolution. He is never shot at, and thus lives much longer.
You've taken away much that was unique about Lenin and why he became so important. Now, the only unique idea that he could provide Marxism is that Russia was already a capitalist society, and thus there was no need for a bourgeois transitory period between Tsarist Russia and Socialist Russia. But there will be no vanguard of the revolution, no core of professional revolutionaries... he'll want to win democratically and keep democracy. In that sense, he'll lead the RSDLP away from the position of simply being pro-labor to actually creating a socialist, soviet government that will revoke capitalist ideas. It won't be a serious enough break with the rest of the RSDLP that he'll lead a split, but those ideas will become more and more popular.
After that, simply follow my timeline,
A Lenin-less World, and it'll be mostly the same. This POD effectively kills the Lenin we all knew, too. What does that involve? A successful anarchist-led putsch against the Provisional Government in July 1917, an All-Russian election by August or September, a Constituent Assembly organized by the end of 1917, the triumph of the Socialist-Revolutionary party, an earlier and more successful Treaty of Brest-Litovsk, a slightly longer and bloodier Great War, a harsher peace, a smaller Poland, a larger Hungary, a democratic federal
Rossiiskaya including the Baltic countries...
