I have found crowdsec 1.4.3 for armv7 and is working good on my Linksys WRT1900ACS
I just replaced my binary files crowdsec and crowdsec-cli with the ones in here: crowdsec-1.4.3-r1.apk.
I could not work out the same for cs-firewall-bouncer-0.0.24-r3.apk so I stay on "crowdsec-firewall-bouncer_0.0.21-3_arm_cortex-a9_vfpv3-d16".
I am lazy I know, but there is any plugin workaround for crowdsec?
I'm currently working on a new package for the Crowdsec-firewall-bouncer with uci configuration file and will afterwards try to set up a luci package for configuration as well.
No date yet.
There is a trick to installing cloudflare bouncer to OpenWRT? I can't found in the repo.
I'm making progess so this is a call for testers. 
What I have achieved so far: I have a crowdesc-firewall-bouncer package that is working with OpenWrt 22.03. It uses a uci config file which at the moment looks like this:
config bouncer
option api_url 'http://cs-lapi:8080/'
option api_key '*******************'
option update_frequency '10s'
option deny_action 'drop'
option log_prefix 'crowdsec: '
option ipv4 '1'
option filter_input '1'
option filter_forward '1'
option input_chain_name 'crowdsec-chain'
option forward_chain_name 'forward'
option input6_chain_name 'crowdsec6-chain'
option forward6_chain_name 'forward'
list interface 'eth1'
list interface 'wg1'
option enabled '1'
option deny_log '0'
option ipv6 '1'
I also have a first Luci package available:
I'm currently working on a AVM Fritzbox 4040 so the target is ipq40xx/generic.
It looks nice
