Good catch!
According to the AS1117 datasheet (which is the one available as basic part at JLCPCB) an 22 µF tantalum capacitor is recommended to guarantee stability (I have 4.7 µF ceramic).
Also I found the problem that I don't fulfill the minimum load requirement (10 mA) to guarantee voltage regulation when all LEDs are off.
I replaced the LDO now with the XC6206P33PR (SOT-89). The SOT-23 variant should be able to handle the expected heat dissipation but I go for the SOT-89 for more robustness (even if it is a extended part at JLCPCB).
As basic part alternative there is the HT7533-1 but there I found no information in the datasheet about stability and recommended capacitor type. Only that the typical application is with 10 µF. So if someone wants to try, go for it.
