You can possibly use a cheap chinese TV Media Box (about €35 for a decent one from Aliexpress) to stream Live TV over the Internet and then just connect it to the TV via HDMI.
In my experience those things aren’t loaded with crap and have no Ads (for some, there are even things like libreElec if you want to get full control of it) plus it makes engineering sense to keep the smarts separate from the dumb TV (the actual dumb part of a TVs lasts a lot longer than the typical period between video streams moving to newer and better encoding methods - and decoding of those is done in hardware, not software - so if the smarts are in a separate cheap box, it’s a lot cheaper to get support for newer kinds of video streams a few years down the line and keep the TV than to replace the whole TV just to get the newer video stream decoders)
Personally I use a Mini-PC with Linux and Kodi, but Mini-PCs are more expensive, require more expertise to set up and I do a lot more than just streaming live TV with it.
Word of warning, loads of those are full of hidden malware that will attempt to infect the other devices on your network. Probably best to make your own every time.
