No,the logical conclusion is that, on the contrary, liberal democracies end up as authoritarian legalist regimes, as they progressively need more and more laws and enforcement to catch criminals who evade them.
You can see this clearly with the constant inflation of AML laws in the EU, which become more and more restrictive and invasive each year, without any clear effect.
The US does not feel like they are into adding regulations, would you say they are less likely to end up authoritarian?
There are multiple ways to end up an authoritarian State. You can add many regulations, then have someone come to power and use those regulations to repress society (a good example would be Germany in 1937), or have a weakening of the institutions protecting citizen's rights, which is something the US is experiencing.
It has started before Trump, I think that a turning point was the Patriot Act, but Democrats didn't overturn it and picked their ennemies, too[0].
