Yes, to open the channel towards your node. But that is only for few seconds, because Dunder LSP works with 0-conf channels. That means user will receive instant the funds. and can send them out immediately. It's all an automated process...

Is that a risk? Very minimal. As I said before, a LSP rugpulling a user for a meaningless amount of sats for opening a channel is dumb and counter-productive. LSP is interested in having more channels from which will charge fees forever, not scamming people for a 100k-1M-5M sats channel.
