What are they looking for at the moment?

The LHC is a discovery machine, so a large number of searches for new physics as well as measurements of known physics can take place at the same time.
The idea that it is a single-trick experiment is a misconception. Its a quantum statistical experiment where proton collisions at high energy yields random particles based on the probability of specific interactions taking place.

i am interested to know about the tech stacks of the website i.e., how the data is displayed

These are screenshots taken from SCADA screens.
Architecture briefly explained here: https://accelconf.web.cern.ch/ica05/proceedings/pdf/O3_005.p...
I also want to mention EPICS which is used by quite a few physics and telescope projects: https://epics-controls.org/epics-users/projects/
When CERN Was looking at software they found EPICS wasn't up for the task at the time: https://cds.cern.ch/record/532705/files/ma1o06.pdf

it's just an img tag with an image that is updated a few times per minute, guessing it's a screenshot of some sensor terminal at cern? :D
The LHC also has a public Grafana (mostly for cryo stuff): https://dash.web.cern.ch/dashboards/
And there used to be a very fancy LHC dasboard at http://meltronx.com/index.html
Unfortunately the site breaks with HTTPS and modern browsers (mixed content isn't allowed anymore, and they never updated it). It has to be http://.
