In 1914 there was an alternative in form of the Russian Empire which was seen as something that could absorb a lot of military pressure from the Germans(hard to argue it didn't).
In the interwar period the alternative to little entente(which by itself was more directed towards containing revanchist Hungary or perhaps Austria-Hungary revived) and Poland was the Soviet Union, which didn't have direct border with Germany meaning it wouldn't divert anything away from France and on top of that due to it's ideology it was a difficult ally(the Empire may have been just as alien for the French Republic, but they also didn't invest in ideological takeover of it) that was seen as potentially unstable and its military as untested(the last show of force against peer opponent was the Polish-Soviet war which the French expected Poles to lose).
The real way the French could've fixed the interwar situation would be to realise the time has changed and their real issue would be Germany deciding to remilitarize with the solution being an army that can be sent on a limited war that would force them to go back on that. That would require a larger professional component and understanding that some units will function without being split in 3 and reinforced with mobilised reservists, but the third republic didn't trust the military so that wasn't going to happen.
