Depending on your field, it may be possible that you spend an increasing amount of time doing research and less time having to teach classes as you gain seniority. However, in academia, research is always going to be at least somewhat contingent on mentoring students. There is no way around this. The service aspects of the job, although usually small, will not decrease as you go along.
If you are in a STEM discipline, there are likely many jobs in "industry" that could be more fulfilling for you (and more lucrative). I would look there with strong consideration of shifting career paths. If you have obtained tenure at a quality university, you likely have much of what it takes to succeed in "industry."
Note that there is nothing magical about tenure in STEM in my opinion. My non-university job does not offer "tenure," but even if I somehow was fired, they would need to buy out my contract and I would just go and find one of dozens of STEM research jobs out there in the near geographic area. It's sort of like tenure by abundance of employers.
These things being said, note of course that almost every research job is going to come with some mentorship and service responsibilities. I work outside of academia on government funded research. We have to mentor postdocs and grad interns occasionally. I have to attend meetings and sit on committees. Getting along with colleagues is of course part of every job.
Also note that university positions have certain job benefits that most people do not get. Academics often have large winter and summer breaks. You set your own hours. You have access to a large university library. Sometimes faculty get discounts on university events and facility access (gyms, museums, concerts, etc.)
