I can understand your thought processes here of using Link Aggregation to deliver 2gbps (1gbps + 1gbps) to the router to take advantage of the higher speeds of the 10gbps service and add some redundancy to the connection. However, I don't think it will work, at least not long-term.Can an appropriate LACP enabled switch be used to feed two rj45 aggregator ports with a connection to the ONT?
Maybe, but yes if both the switch has LACP and router has LACP.

Our ONT provides a DHCP address to the device plugged into it (the switch in your example), so you shouldn't use a switch between the ONT and router or else there will be a flood of devices requesting/receiving DHCP addresses from the ONT, which can cause connection issues later down the line requiring you to contact support to clear the IP table on our end.
The typical set-up with switches for our service would be ONT > Router > Switch. This allows the router to still handle the routing of IP addresses to devices while also providing multiple 1gbps-10gbps ports (depending on what your switch and router can handle) for multiple Ethernet connections to the service.
Although, my knowledge of Link Aggregation is limited, so there's a chance I have a misunderstanding of the overall function, but to my knowledge, it probably won't work long-term.
I hope this helps.
Kind regards,
