Please help
keep and eye out for this issue: https://github.com/greatscottgadgets/hackrf/issues/668

I have seen comments and github issues about HackRFs being damaged by high power transmissions. I live 500-600 meters from an airport, should I be worried?
I have read about this issue on github (have been some reddit posts over the years as well), originally in #541 which has now culminated in an ongoing investigation #974.

Which SDR should I rather buy?
However, unlike your sensitivity issues, i dont get any birdies. i have a TCXO though. (https://github.com/greatscottgadgets/hackrf/issues/216). it seems its related to clock drift calibration without one. However this is something most SDR's suffer from, as a cost saving measure. Most RTL_SDR's suffer from this as well ("rtl sdr blog v3" comes with a stable TCXO, resolving the issue.).

External LNA and broken TX
I assume this is the case since I found a GitHub issue talking about blown TX: https://github.com/greatscottgadgets/hackrf/issues/1051 And I followed the recommendation of using hackrf_transfer -c with both -a 0 and -a 1. With a separate RTL SDR tuned to the output frequency I can see a very low power CW signal with -a 0. With -a 1 there is no output. This seems to match the results in the issue.

Samsung phone
If you're talking about building attachments to work with a phone, you're almost all the way there to a standalone device anyway. You might want to look into HackRF and pwnagotchi for inspiration.

Is there any software for rtl sdr that can read signal and emulate it, for windows or Linux? PLEASE HELP!
If you get a HackRF there's a utility called hackrf_transfer which can record a block of spectrum and then play it back.

Littlefs – a little fail-safe filesystem designed for microcontrollers
We use littlefs in Flipper Zero's firmware[1] for storage in leftover flash space after the main firmware image. Flipper implements a virtual FS, where both external SD card and internal storage have own mount points. SD card is used for storing apps and user-created data, and internal littlefs contains persistent data like BLE pairing, system services configs and such.
We never had any issues with littlefs - however, it cannot be easily repartitioned when amount of available leftover space changes with firmware updates. So on installing an update, it gets fully backed up to SD card, reformatted and later restored.
