Yes and no. Interferometry increases the resolution, but if we want to know more details about exoplanets we absolutely need the most light we can collect which means we need the largest telescopes possible.
And we also have to keep in mind that there are to fundamentally different ways telescopes can work - optical telescopes use particle detectors, they can only use interferometry if physically build as an interferometer and performing the interferometry before detecting the light. Which is possible, but challenging: https://www.eso.org/sci/facilities/paranal/telescopes/vlti.html
Radio telescopes on the other hand detect waves, with a high time resolution it is possible to calculate the interferometry afterwards. That's what the EHT does and why it can span the whole globe. By the way, it isn't even the largest "telescope" we ever had, the Russian satellite Spektr-R/Radioastron operated a decade ago and allowed to create a radio interferometer 10 times the size of the earth.
When we want to detect life radio telescopes won't help us. They might if there is a technological advanced civilization like our own, but that's it. We need optical/spectral evidence and we will only get that using the next generation of giant telescopes. Even the VLTI which combines four of the largest optical telescopes that exist today is dwarfed by the ELT (currently in construction) which will collect about 7 times as much light.
