Germany doesn't have an agreement with Qatar but there is another player that you haven't accounted for. US going to apply pressure on the oils cartel with NOPEC bill that allows US to sue the oil cartel or its members, force them to increase their oil production or risk of their assets frozen in US banks or no business with US's entities. If those cartel doesn't like it, they can open up a shooting war with US which I'm sure US will be happier to have more oil country under their control.
This has nothing to do with gas supplies to Europe. However, the best thing the US can do about the oil shortage is to increase its own production or get back into strategic reserves. Attempts to pressure the cartel are ridiculous.
Even Brazil said "no" to the US request to increase oil production, arguing that it was a matter of business strategy, not political speculation.
