What happened in Samourai is that a non-custodial wallet was charged for "allowing" money laundering. That is so broad that anything can be considered likewise. We hadn't experienced such a case before, it was mostly mixers which were getting shut down, and lawfully, as they were transmitting money. Now this is a game changer. Joinmarket, Electrum, Bitcoin Core, DEXes, C++ libraries, Internet providers, this forum-- anything can be considered a money transmitter after Samourai.
I don't believe things will go that far, and the reason they were shut down is that they enhance privacy for BTC users, and we all know the government is targeting any service that enhances privacy, by charging them for allowing money launderers conceal their tx's. So Electrum and some of the services you mentioned do not fall under this category, because they do not enhance privacy or make it hard to track BTC tx's.
