On my LG 17Z90R-K.ADS9U1 (running Linux Mint 21.3) the TLP STOP limit worked up through and including kernel 6.9.6, and failed to work on kernel 6.9.9. I haven't tested on 6.9.7 or 6.9.8 but as the OP saw the failure on 6.9.7 (or maybe 6.9.8) I would guess that the problem began in 6.9.7. I can test 6.9.7 and 6.9.8 if that would be helpful. The keyboard backlighting appears to be functioning on 6.9.9.

Here's the (unsurprising) diff of "tlp-stat -b" on 6.9.6 vs 6.9.9:

5c5
< Supported features: charge threshold
---
> Supported features: none available
7,11c7
< * vendor (lg_laptop) = active (charge threshold)
< Parameter value range:
< * STOP_CHARGE_THRESH_BAT0: 80(on), 100(off) -- battery care limit
<
< /sys/devices/platform/lg-laptop/battery_care_limit = 80 [%]
---

> * vendor (lg_laptop) = inactive (laptop not supported)

Attached are the output of "tlp-stat -s -b -c" for both 6.9.6 and 6.9.9
