The heat from those bulbs was used to keep the content over 0 degrees Celsius when the fridge got colder than the set temperature (e.g. very cold room in winter) to prevent the goods in the fridge from freezing.
That’s what I know about this topic. Valid for Germany, don’t know how this is handled in other parts of the world.
No. There is a thermostat for this purpose. You can open a fridge 0 or 50 times per day and it will keep the set temperature (on average). If things freeze in your fridge, it does not mean you don’t open it enough – it’s misadjusted or faulty. And the evaporator (cooling) tubes are in the back wall, on which water condenses and does get cold enough to freeze sometimes. Anyway, the droplets fall into a drain and a narrow tube carries them out, usually onto a little tray on top of the compressor, whose heat helps the water evaporate. Replacing the bulb with an LED has no effect besides decreasing energy usage.
In fact, if an E14 LED burns out, you can often remove the plastic cover, find the burnt LED chip (if that’s what failed; look for a black spot), pry off all its plastic parts and short the contacts by scraping the aluminum/copper pads together with a knife. A soldering iron works better but I cannot bother waiting for it to heat up. Another LED chip will likely burn out sooner or later if it runs hot again but it will not get over 50 °C in usual fridge operation. Check if it fits into the fridge and add an aluminum foil reflector to redirect light if it helps. I did this in some Liebherr, Zanussi and Electrolux fridges, which I believe are also available in neighboring Germany. I use 2~4W “candle” bulbs for this because they are tiny without the plastic diffuser and not great for general lighting in most fixtures. If you don’t have failed LED bulbs, there is a free selection at dm or Lidl near the entrance. Be quick and sneaky but don’t take any CFLs (center of mass or shining a phone flashlight through the milky glass helps reveal a CFL tube if coiled inside). If you accidentally take a CFL or fail to fix an LED, return it on your next visit with an obvious hand movement so that your activity appears legitimate overall.

Wait what’s this about a free selection? Why would you have to be quick and sneaky if it’s free?
Sort of sounds like… shoplifting with extra steps
