The national media in Ireland has always been partisan. In the old days, you were an Irish Press family or and Irish Independent family, with a very small sprinkling of Irish Times families.
Nowadays you have access to a whole array of news sources, operating from different political angles or none, and it's actually easier than it was in the past to find dissenting opinions, weight them up, fact check them, and make your own mind up. Let's not forget that there are also books and articles to read, which refer to sources you can follow up and weigh up.
The spanner in the works is social media, when any old madey-uppy guff can get presented as 'fact' - in fact, when you see someone on SM starting a statement with 'FACT:' it's a red flag, because it probably isn't.
Another thing that happens a lot these days is people using words in a very exaggerated way - trans rights activists saying they are the victims of 'literal genocide' for example, or people claiming that Ireland has a 'third world health system' - both of these are insulting to people suffering actual genocide, or people suffering and dying where there is no health system at all.
I think 'Ireland is totalitarian' falls into this category: we are a parliamentary democracy, with a written constitution, which runs fair and open elections - yes they are free and fair, despite some groups casting aspersions on the people who run our elections to try to undermine their validity.
We may not like some of the people who put themselves forward for election, but that's not the same as not having free elections.
So no, OP, I do not think Ireland is even remotely a totalitarian state, in the accepted meaning of 'totalitarian'
